Added Russian translation for the launcher.
Added a Russian template for a new game.
Remove the shift+Y binding to dump styles.

It wasn't used all that much, and it's made redundant by the new
style inspector.
Rename place_images -> get_image_bounds, add testcase.
Merge pull request #272 from tlm-2501/master

Russian translation.
Implement renpy.retain_after_load()

This does not rollback data that is changed between the current
statement and the next checkpoint. The main use case is to be able
to save while a screen is displayed using call screen.

For example, a user can be assigning points to a character in a
screen, save, load, and have the same points assigned.
Do not strip docstrings in run.sh.
Document renpy.retain_after_load().
Check in generated docs.
Check in images used in testcases.
