Adds a checkbox "Use web profiles instead of legacy v1 profiles" to System->General preferences
Adds a button "Web Profile" to the first life tab of legacy profiles (only available on grids that provide a web profile url)
When connecting to an OSGrid, always set the WebProfileURL setting to whatever is in web_profile_url, this way we know if web profiles are not supported.
Borrowed translations of the preference checkbox from Firestorm, translators may want to tweak
Translators may want to update panel_avatar.xml as it now has a web profile button, and contents have shifted slightly.
Updated French Translation from Nomade's Zip for MultiWear.
Updated Translations to use basically the same format, and not have some cruft.
Abouts updated to include Spanish translators: Damian Zhaoying, and Franxizco Romano.
