Allow setting a listener target and a modification message.

* Link against liblocale.so and load app catalog.
* Took FontSelectionView from Haiku Fonts preflet, but almost rewrote it to
adapt for WebPositive needs. It's now a BHandler, so that it can actually
receive messages itself. The Fonts version is a BView which is never attached,
and only receives messages, because the window forwards them. Implemented
option to use separate style menu.
* Provide font settings in the Settings window.
* Wired everything to make it work, although I am not sure standard font is
applied. It does work for the serif font, though. Maybe I ought to install
more fonts and check with simpler HTML.
