handle user typos in password popup (nickserv) properly

[jeremyb]

I initially observed this with unreal running anope (irc.mozilla.org) but this seems to happen just as bad (or slightly worse) on freenode.

STR

• connect using a registered nick with no password set in get info
• get passwd prompt popup win and enter bogus pass (add to keychain unchecked)
• on /nick or discon/recon there is no obvious way to change remembered pass and Colloquy keeps sending the bogus pass
  • Workaround I found which worked at mozilla but not on freenode was set get info pass to foo and then /nick or discon/recon. if you then set it to blank then it does work on freenode. not sure if that difference happens reliably though.

So, there are a bunch of issues here and a few prolly deserve their own bug. (yes they are bugs not tickets :P)

• Colloquy should recognize pass rejection
• user should be notified when a pass is rejected
• user should be prompted for a new pass
• there should be a way to force Colloquy to forget a remembered pass (session not keychain) or to specify a new one manually

Password rejection annoyingly leads to a trailing underscore appended to your nick.
