Implemented a BSeparatorView. It can be a horizontal or vertical line/border,
or also a label, optionally with a BView for the label. Some aspects of it have not been exposed to throughrough testing, yet (archiving, label view), the BAlignment support is also not well tested. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31846 a95241bf-73f2-0310-859d-f6bbb57e9c96
