Building TGE1.5 tools under linux

Under linux with TGE 1.5, you can't build the tools out of the box. In fact, I'm sort of surprised the tools build and work properly under windoze given issue #1 below.

There are three issues I've run into so far building the tools:
1) In tools/map2difPlus/editGeometry.cc, gPlaneNormThresh and gPlaneDistThresh are declared as F64 globals. This collides with the F32 declaration of those same variables in engine/sceneGraph/sceneLighting.cc. I resolved this simply with:

svn diff tools/map2difPlus/editGeometry.cc
Index: tools/map2difPlus/editGeometry.cc

 U32 EditGeometry::insertPlaneEQ(const Point3D& normal, const F64 dist)
 {

2) I've always built the tools after doing a clean build of dedicated, i.e. "make clean; make dedicated; make tools". This still appears to be the better way to do this under 1.5.0, however we have a few references to EditTSCtrl::smCamPos and worldEditor::objClassIgnored. I eliminated these with by putting them into #ifndef DEDICATED/#endif blocks.

svn diff --diff-cmd diff -x -w engine/lightingSystem/sgLightManager.cc
Index: engine/lightingSystem/sgLightManager.cc

>       // DEDICATED macro to eliminate the undefined references.

3) Once built this way, I'm getting SEGV's which I haven't had time to attempt to track down yet.

I've tried various ways to get around problems 1 and 2 without doing the things I have above. The above are the best solutions I've come up with so far. Since I won't have much time to work on this until next week or the week after, I'm tossing my unfinished work out for others to review and/or get inspired by, :-).

Edit: fixed reference to #ifndef.
