[Mythtv-translators] A few new strings...

[Nicolas Riendeau]

Hi!

A few new strings unfortunately had to be added to add a new setting to 
avoid a browser crash in the internal web browser.

re:  http://svn.mythtv.org/trac/changeset/26729

The number of strings this introduce is minimal but the gain is great as 
it permit the deactivation of browser plugins in the
internal web browser which, when they crash, bring down MythFrontend 
with it.

Thank you for your understanding!
