svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
BPyMesh.py - own dumb error, was using dir as an arg (which is a py keyword)
object_drop.py - new script, the first to use UIBlock, it drops objects into terrain, either a group or the active object. on teh Z axis or view axis.
