l10n_client 6.x-1.7

This release fixes security vulnerabilities. Sites are urged to upgrade immediately after reading the security announcement:

• SA-CONTRIB-2009-019 - Localization client - Cross site scripting

In addition to this security vulnerability, the following changes have been made since the 6.x-1.6 release:

• Parts of #218516 from Roger López and myself:
    1. Handle the special case when all the translatable text is HTML. Escape the code in this case
     but only after the code was trimmed for length.
  2. Remove HTML tags from translation for redisplaying in selection list after saving. This
     only affects the display in the selection list. Apply the same HTML tag stripping and
     length limitation as in the PHP code. Also implement the (1) special case above.
