Added a number of funtions for keyboard shortcuts.
Modified version of locale files for pushing to Transifex. "." has been
substituted for missing translation lines in README.md since Transifex
expects a non-empty line to match each non-empty line in the English
version.

Transifex also expects spaces around the "=" sign in Mozilla
.properties files.

This Transifex branch should not be merged without stripping out the
placeholder strings.

A Transifex config file defining all of the locale files is also included in
this commit.
Merge from Transifex. Changes include updates to de locale by Armin and modifications to whitespace (and unicode?) introduced by Transifex.
