Fixed a bunch of bugs in the font sub-system:
* BFont::Face() was almost always wrong - also on the server side, _TranslateStyleToFace() was broken. * a clean font was not correctly initialized to be_plain_font * BFont::GetFamilyAndStyle() did not work correctly if either family or style was NULL - which is allowed, and shouldn't have let it abort its task. * FontServer::GetStyle() by ID did not work reliably under certain circumstances (but those were not reached with the current server) * BFont::SetFamilyAndStyle() did not work when family was NULL, and it also never set fFace correctly. * Introduced a FontFamily::GetStyleWithFace() * Renamed some FontFamily/FontStyle methods from ie. GetID() to ID() to match the style used everywhere else in BeOS. * Removed AS_SET_FAMILY_NAME as its no longer in use. * Lots of cleanup and simplification. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14602 a95241bf-73f2-0310-859d-f6bbb57e9c96
