Fixing issues with i18n stuff:

- Make gettext stuff draw-time. so switching between languages
  can happens without restart now.
- Added option to translate visible interface (menus, buttons, labels)
  and tooltips. Now it's possible to have english UI and localized tooltips.
- Clean-up sources, do not use gettext stuff for things which can be
  collected with RNA.
- Fix issues with windows 64bit and ru_RU locale on my desktop
  (it was codepage issue).
- Added operator "Get Messages" which generates new text block with
  with all strings collected from RNA.
- Changed script for updating blender.pot so now it appends
  messages collected from rna to automatically gathered messages.
  To update .pot you have to re-generate messages.txt using "Get Messages"
  operator and then run update_pot script.
- Clean up old translation stuff which wasn't used and most probably
  wouldn't be used.
- Return back "International Fonts" option, so if it's disabled, no
  gettext lookups happens on draw.
- Merged read_homefile function back. No need in splitting it.

TODO:
- Custom fonts and font size.
  Current font isn't nice at least for russian locale, it's
  difficult to read it.
- Put references to messages.txt so gettext can merge translation when
  name/description of some property changes.
