Fix squares showing up on God Tools floater because of tabs being used for xml spacing
Fix Issue 992: Singularity will not allow teleports above 4096, nor building above 4096.

Teleport height restrictions have been increased to 8192
 -The 4096 limit isn't in much of the teleport code anyhow, and it's certainly not enforced.
Building height restrictions are now hooked up to hippolimits, apparently they hadn't been
 -MAX_OBJECT_Z, and hardcoded 4096s now use gHippoLimits->getMaxHeight() instead
 -On floater_tools.xml max_val is left out, instead it is set with the rest of the gHippoLimits edit constraints in LLPanelObject::getState
Fix the spinners on the map and on the god tools floaterbeing too small because of unused label_width.
