"rebuildnodes" directive for MAPINFO

[Xaser]

I'm currently working on a vanilla Doom project that uses some of ZokumBSP's fancy-pants compression features to get a particular map within vanilla limits (yes this is necessary; don't ask), and the GL renderer doesn't like certain things about it.

This can eventually be trivially fixed in GZDoom by adding a "rebuildnodes" directive for the map to compatibility.txt, but since I know about this problem in advance, it'd be nice to declare "rebuildnodes" in MAPINFO in advance to solve the problem without requesting a patch. So here we are.

[If this is No'd, expect a compatibility.txt request for this particular map sometime in the future. ]

What the hell is that node builder doing here that it breaks the renderer? Vanilla nodes will be rebuilt anyway because the GL renderer has no use for them so under normal circumstances this flag should be totally redundant for a vanilla compatible map. In addition, the BSP's contents are never actually rendered directly, they are merely used to traverse through the map.
