SeaMonkey chatZilla strings

Hello localisers,

chatZilla is being embedded into SeaMonkey and the strings for that are due to land shortly which means they will be exposed for those locales that currently localise SeaMonkey.

You may spot a temporary bump in missing strings for SeaMonkey before the strings are copied from extensions/irc into suite/chatzilla. A script will run in the background to copy these automatically and, for most locales, there shouldn’t be many new strings to localise.

Thank you for all your work.

Regards,

Ian
