protocol: skip Haze's IRC implementation

Users should be using Idle for IRC, and not Haze. This is implicitly
codified in the widgets array kept in tpaw-account-widget.c. Otherwise,
if Idle is absent we would still be advertising IRC support in the UI,
only to crash immediately afterwards.

All said and done, it is saner to support one single implementation of
a protocol.

Use "Remember password" everywhere

It shouldn't be "Remember Password" according to the HIG.

account-widget: use the "error" CSS class on wrong entries

That's the proper way to do as GTK+ defines this class for exactly this
purpose. Our current code was pretty hacky anyway.

This also has the nice side effect of fixing a bug making the text unreadable
when selecting it from the entry.
