Localisation / French translation file

Hi,

the french translation file included in the current version of the theme is corrupt and contains very bad translations. I fixed the file and improved the translations. You can get the fixed file here:

There are still some problems with using this theme in multilingual settings.
Foremost is the fact that the plugin uses an old version of the ‘timeago’ jquery module without actually setting it up for localisation.
