New way of generating the grub keymaps. There are based on X keyboard
layout and previously we tried to load them from the console keybaord
layout.
getinput function for grub now add a space after the prompt when asking
for input.
Translations have also been updated (and a lot of errors were there).
Transifex configuration commited as there is no private information
there and that could help to be in sync with transifex translations.
