Fixing various problems with MF_SOLID collision
(I, toast, wrote the original merge request, but Alam made this merge request because I made a mistake. Twice. In a row.)
* Solid objects are now no longer intangible when your z is less than the other object's.
* I originally thought the bug was limited to just solid objects on slopes (hence the branch name), and was wondering about undesired side effects - but looking at this gfy, this was a major bug that slopes made easier to expose.
* Unfixed = http://gfycat.com/BareLimitedCavy
* Fixed = http://gfycat.com/JubilantOffensiveGar
* You now properly lose your momentum when jumping at a solid object.
* The way I fixed this was a hack, but it was originally a much worse hack which resulted in very bizzare physics issues, so...
* Unfixed = http://gfycat.com/ShockingAbsoluteArthropods (also demonstrates the first bug)
* Fixed = http://gfycat.com/EmbellishedCourageousGordonsetter

The problem was that MT_OVERLAY's default radius and height were never getting changed from 1*FRACUNIT, and that meant that when you spindashed, the game considered it completely below the surface of the flat you were standing on. Since you're not usually clipped on flats that don't belong to FOFs, we didn't notice this aspect of the issue sooner.
(SORRY FOR THE MULTIPLE MR'S AGAIN I TOTALLY SUCK AT REMEMBERING TO MAKE SURE IT GOES TO NEXT INSTEAD OF MASTER)

v.drawScaled negative scales fix
Lua now errors if you try to use negative scales with v.drawScaled, rather than crashing as it does in 2.1.16 currently. Not much else to say here.
See merge request !126
Fixing FF_REVERSEPLATFORM clipping fixes
Forgot the case where == 0.
Tested by @wolfy852 in Top Down, where the bugs this caused were first discovered.
See merge request !121
Even more slope-related fixes
What it says on the tin pretty much:
Currently included fixes:
* Pusher specials applied to FOFs did not properly account for slopes applied to the bottom plane; this probably was just a minor slipup that appeared on adding the support in the first place, I take it? (some waterfall in the last section of SUGOI's Fudge Canyon is the only place I can think of offhand where this bug is noticable)
See merge request !114
Treating " as whitespace in TEXTURES (and animdefs too i guess)
SLADE adds this character in its TEXTURES editor and makes SRB2 cry unless the lump is manually edited; this just treats it as whitespace so we don't have to think too hard about it.
Also, two I_Errors now refer to the correct lump name.

Basically, it manually sets *_FOUND, *_INCLUDE_DIRS and *_LIBRARIES instead of using find_package. Frankly I have no idea how well what I've done works currently though, not even sure if I've set the _LIBRARIES variables correctly. Again, it's WIP work, this can probably be fixed eventually I suppose.
HOWEVER, since these changes to PIT_CheckThing do raise questions about whether there may be unintended side effects here. As a result, I may remake this for internal only if necessary.
