Debugging tests paid off, fixed a ridiculously silly bug
that was preventing light cache from working on some
people's systems (but went just fine on both my windows pc
and mac). I have no idea how the original code even worked
at all, it really shouldn't have.

But fixed now anyway! Thanks a bunch to Zanqdo for patience
in helping me pinpoint this.

removed debug stuff

and more debugging

more testing code

Just adding some temporary testing code to help try and find a bug.

Snapping sketch to bone was using untransformed head/tail. Fixed.

Gesture for delete selected (experimental): figure 8 (gesture crossing on itself twice)

Correct handler for floating panel (close button wouldn't work)
Redraw event on floating panel buttons
Correct limit for Number of Fixed subdivision button
Fix off by one error in fixed subdivision loop.

default opengl static locations was to try /usr/libGL.a, use the oprngl lib path instead - /usr/X11R6/lib/libGL.a

Missing NULL check causes crash on Ikey when no active object.
Error is bad enough to go for a retag... hrmf!

Report from Ernesto (der|kunstler) Mndez in irc. Thanks a lot!

New splash c file (now gimp png) and bumped version to 2.48.1 to make it
even a bit more clear.

After this commit we'll tag svn (gasp!) and then go build!

Part one of the release update commit

* Minor cleanup of SCons files

- cleanup of boolean usage - use True and False now instead of 'true'/'false' or 0/1
- changed SConscripts accordingly

* Did some small tweaks to how density is used with light
cache - it makes some very good improvements clearing up artifacts:

added an option for python Draw.UIBlock(func, mouse_exit) so moving the mouse outside the popup wont close it.
Stops FBX Export and OBJ I/O from flickering a lot.

make sure BPY_Err_Handle clears python errors, even if the exception cant be printed. Added PyErr_Clear() incase there are other references to exception data (sys.exc_info() from python)

* comment fix

* Fixed a bug in copying (making single user) a point density texture
