Experimental Lua Globals Explorer 3.1

Forgot to remove timeprobe()

Improved performance
Before, every key-value pair created a new table which meant a lot of garbage collection pressure. Now, after a big rewrite of the data structure, everything is in a flat array, that is reused in GElua, achieving about 10x performace for big tables.
The sorting speed also improved with this.
Improved error tolerance
added pcalls for userdata and cdata, which means it shouldnt crash (and if it does report it to me so i can fix it)
Multi-window support...

clicking on the value of userdata no longer fatal-lua-errors, but instead copies the value
Thanks to fillman86 for the bug report

Added support for cdata cause i may have completly forgot about that (stuff like vec3 or quat)
Added the ability to browse __index
Fixed the crash when window too small
Updated the rendering of the separators
Fixed some other small bugs
