webtranslator - l10n: I started to write the file's locks, when a

Log Message:
-----------
 I started to write the file's locks, when a translator pick a file to translate
that file is locked from 0 to 15 minutes. The unlock process for a file happens
in 2 ways:

 1) The translator pick another file to translate
 2) If the translator has got a file locked and he don't do anything in
    15 minutes an extern process have to do an unlock on it.

  ** Extern process ** could be a function called by cron

    1) 80% done
    2)  0% done
