Move English messages from po/en_US to po/en

When using gettext, the bot will look for English messages in the 'en'
locale, rather than en_US. This causes some Ruby GetText version to
not find the .mo files, which used to be stored as en_US instead. Since
Ruby's GetText seems to be too stupid to fall back to en_US when en is
not found, we move the messages to en.

This is also probably more correct from a linguistic standpoint, since
the messages are actually mostly British English due to the bot origin.
