Grease Pencil Bugfixes:

* Fix for #17808: Can't compile using SunCC - gpencil.c uses DOS line endings. 
Added some svn-properties on gpencil files and also keyframing ones that I added, so that this shouldn't be a problem anymore.

* In Node Editor, it is now possible to close an open Grease Pencil panel when there is no node-tree being shown (i.e. after switching between node editing modes)
