Merge pull request #261 from vbkaisetsu/fix-doc

fix typos
QuickSave shouldn't take a screenshot while in a menu.

Fixes #251.
Do not include binary files in the source distro.

Fixes #256.
Change the tutorial music to Sunflower Slow Drag.

This was the music used (as a midi file) for the very oldest versions
of the Ren'Py.

We use a 1994 recording by the US Marine Band, taken from
Wikipedia. It's public domain due to age (of the original) and due to
being the work of the US Government (for the recording).
Add Preferences("display", "any window").

This is selected when in any windowed mode, and changes back to the previous
window size.
Add renpy.place_image.

This returns the bounding box containing an image that's currently
being shown.

Fixes #255, or at least the underlying request.
Start work on style generation code.

First off, we create a list of prefixes and the order in which
they are stored.
Add style properties and synthetic properties to generate_styles.
Generate style property functions.

These are functions that take the value being assigned to a style,
process it if necessary, and assign it to each style's cache.
Fix renpy.import_all()

Doing:

    import renpy; renpy.import_all()

now works, so we can use it in test code.
Start generating the Style class.

The style class has properties supporting set and delete for each
prefixed style property.
Build styles and retrive attributes from a single style.
Break styleaccel up into two files.

The new styleclass.pyx file contains the Style class. We compile it
separately since it's huge, and changes rarely.
Add various fields to the pxd.
