The BeOS-specific part of the BeOS (and Haiku) port, modeled mostly from the GTK version.
Some fixes are needed elsewhere but non-obvious ones I'll post on the mailing list for discussion. Currently it opens windows with a toolbar, url and status bar, a (yet empty) menu bar. Rendering seems to work including scrolling at scale 1 (other non-tested). framesets seems broken though. svn path=/trunk/netsurf/; revision=4253
