loudmouth(XMPP): fixed a crash when a message comes and we don't know who it is for
loumdouth(jabber/XMPP): change some actions' icons so they appear correctly
Made the gtk+ menu builder translate icon names to gtk+ icon names
Changed icon names from "gtk-foo" to "foo" when the piece of code was supposed to be gui-independent

Let the gui code translate to what it wants!
Unbreak icons -- stupid mistake!
loudmouth(jabber/XMPP): use existing icon for the start/continue chat menu entries
Updated French translation
OPAL: Fixed presence subsciption problems.

Presence notifications were sometimes broken when:
- adding a new presentity
- enabling an account afterwards
- starting with an account enabled (race)

This is now supposed to be fixed. It is a workaround OPAL limitations.
OPAL does not allow subscribing before we are registered to an account.
GUI: Improved accounts window.

The checkbox was misleading: it could not be toggled/untoggled.

It has now been replaced by a nice icon indicating the account status.
The icon is synchronised with the published user status. That way, the
user rapidly knows which accounts are active or not, and what is the
published status for those accounts.
Roster: More offline/online fixes.
Updated Latvian translation
OPAL: Adapted to the new bitrate API.
Accounts Window: Fix button sensitivity.
Fix the h323 preferences activation
Check for newer versions of ptlib & opal

Fixes bug #678836.
Added another case for the translation "ui-less icon -> gtk+ icon"
Use ui-less icon names in places which are supposed to be ui-independent
Fix crash at zoom out in call window
