Set up work for making a 3.5 prerelease. Set version stuff to 3.5.0-rc1. Copy the CHANGELOG from 3.4-working. Rename the obt-4.0 and obrender-4.0 pkgconfig stuff to obt-3.5 and obrender-3.5 Rename the "render" directory to "obrender" so that the public headers can be installed in <obrender/*>
set the right version in the new render and obt .pc files
setup versioning for libotk that is separate from libobrender (and libobparser for now), and bump library versions up to 4.0. also make the render versioning more explicit that it's for the render library not all of openbox
look mom, I made an openbox toolkit
