Merge pull request #29 from putnik/master

"File:" namespace for images, better support of galleries
Merge of upstream plus a few additions and notes. Removed ctrl+s keymap as it is not compatible with my workflow.
Added edits to mediawiker.py and (windows) keymap, should be considered part of previous commit.
