Solve Issue 521: Web profile support

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.
