Use cairo for drawing
GDK drawing does not exist in GTK 3 anymore. We now use cairo for
drawing. This means that the graphics window now corresponds to a
GtkDrawingArea, and we use a cairo surface as a backing store.

Replace deprecated signals
The 'size-request' and 'expose-event' signals now don't exist anymore.
'expose-event' is simply replaced by 'draw'. We used 'size-request' in a
slightly different way than it was supposed to be: connecting a handler
after the default 'size-request' handler run, ensured that the handler
was run after the GtkTextView finished validating text positions, so we
could scroll the text view to the end after printing text to it. Luckily,
'size-allocate' works the same way in GTK 3.

Replace size-request by minimal height-for-width
The size-request method is now gone, in favor of height-for-width
allocation. The height-for-width implementation is currently minimal,
as described at
http://developer.gnome.org/gtk3/stable/ch24s02.html#id1328275
This could be made much nicer.

Remove deprecated member access
GObject classes aren't supposed to have their members accessed directly
anymore. Instead use accessor functions. In the case of our
gtk_text_tag_copy() function this requires some clever copying of
properties ;-)

Implement new name mangling
The Glk 0.7.4 spec has new recommendations on what characters should
be legal in filenames and how to make sure that files created by
different Glk implementations are interoperable.

Implement recommended file suffixes in dialog
When creating a file with glk_fileref_create_by_prompt(), there will
be a file filter active for the recommended file extension. For
fileusage_InputRecord and fileusage_Transcript, there will also be a
filter for text/plain files selectable. In any case there is also an
"All files" filter selectable.

Prevent unnecessary regeneration of VAPI
Vapigen doesn't update the timestamp of the VAPI file when the
contents don't change; so when the GIR changes but the VAPI doesn't,
the dependency tracking got confused. This updates the timestamp
properly.

Added a Python player!
It crashes half the time because GObject Introspection isn't actually
officially supported with GTK 2. However, it's a simple player that
shows how to use Chimara in Python. We don't even have to write any
language bindings, thanks to the power of GObject Introspection! But
if we want to do anything serious with Python, we will need to port to
GTK 3 first.
It's a straight port of the C player, but it's 300 lines instead
of 1200 ;-)

Identified two more entry points
This fixes an obscure bug! If you create your ChimaraGlk object
not with chimara_glk_new() but with g_object_new(), then the library
init function was not called. That caused a crash when trying to
access the thread-private data.

Add API to start plugins using GFile
To complete the API, we should have functions that start a plugin using
GIO's GFile API. It's easier for navigating the filesystem in language
bindings such as Python.

Add API to unload plugin module
This is a workaround for a very complicated bug. When you have more than
one ChimaraGlk widget opening the same plugin, then g_module_open()
doesn't dlopen() the plugin again; instead, it just adds a reference to
the open module.
This means that all static variables in the module are not reinitialized
when the Glk program starts running in the second ChimaraGlk widget.
This problem needs to be solved either by eliminating the static
variables from the plugins, or making sure that different ChimaraGlk
widgets open their plugins separately.
This commit does the latter, by adding API to unload the plugin module
(chimara_glk_unload_plugin()) so that ChimaraGlk widgets that run the
same program but not at the same time have the option to unload the
plugin in one widget before loading it in the other. Specifically, this
is the use case of Inform 7.
This does not fix the use case where two separate ChimaraGlk widgets
want to run the same program at the same time.
Finished babeltest, it now does all of the following:

Keep an EOF mark for memory streams
Seeking to seekmode_End in a memory stream should move relative to
the last written position in the buffer, not the end of the memory
buffer. This brings the behavior of memory streams into line with
what would happen in a file stream.

Fix obscure C stdio bug
You cannot switch between reading and writing a file stream without a
call to fseek() in between. This borrows Andrew Plotkin's solution of
keeping track of what the last operation was and switching if
necessary.

C stdio trickery for read/write mode
As pointed out in the new version of the Glk spec, when opening a file
for appending, you cannot seek in it. We must open the file for
appending, to make sure it is created, then close it and reopen it
for read/writing.
