Replacing PluginPref? API with Request API

There's some amount of duplication between the PluginPref? API and the Request API. This should be fixed. Finch currently converts a pluginpref-frame into a request-fields (gntplugin.c:process_pref_frame), which allows it to reuse the request ui. Each name and label of a PluginPref? maps one-to-one with a RequestField?. However, a PluginPref? can impose some restrictions on a value (eg. min/max values for an integer preference), which a RequestField? still can't do. So some additions to the request api will be necessary.

Small features

• Allow creating chat-rooms and inviting a bunch of people at the same time. Prpl-option flags can be used for protocols that support it (MSN, Y!M currently?). There can be a menu-item which will be enabled only if one of the connected accounts is capable of doing this. The callback request-dialog will show only the capable accounts (using some filter-function) and use siege's multi-user selection dialog.
• Improve the IRC protocol by adding support for some commonly used non-standard stuff. Possibly open an IM for each irc-account where all the non-standard messages can be dumped (somewhat like the server-tabs in some other irc clients). This way, users will see some output for, eg. "/mode #channel +b". I don't personally use any of this, and the current prpl is just fine for my use (send and receive messages). But I believe this is a widely requested feature. Since we do cater to popular demands, I think this can be included in the list.
