Optimisation of P_GetMobjGravity (relevant for slopes)
Cleaned up some performance issues in Skytop Zone (2.1.16: THE SUGOI UPDATE) arising from some inefficiencies with P_GetMobjGravity. FPS drops only occasionally to 34 now, which is a big improvement when I was frequently getting 27 in Salt's 15andahalf.exe.
(I also tested in a build of 2.1.16's first release candidate, and was getting drops to 16! So SOMETHING improved since then, but this was the major issue.)

Also, the particles made via spindashing in shallow water are now located behind the player. This does move the running particles too, but that's okay.
* Fixed bug where being pushed off a platform whilst charging a spindash would leave you in your charging frames instead of your rolling ones when you hit the ground (http://gfycat.com/MassiveThreadbareItalianbrownbear for how it works now, http://gfycat.com/MarvelousEnlightenedAuk is how it used to work)
* Fixed bug where spindashing on top of a bubble spawnpoint led to you being able to move around in spindash frames (no gif since obvious desired behaviour is obvious)
* Spindash animation speeds up the faster you'll shoot off.
* The spin charging mechanism is now scale-independent, and only multiplies by scale when shooting off - less FixedMul calls, and potentially deals with weird quirks of changing scale whilst spindashing that nobody's discovered because there's no place to find that in the main game!
Also:
* Climbing animation defaults to rolling instead of walking, because what.

Skewing direction is decided per in-level wall by the Lower Unpegged flag on in-level linedefs themselves, since they already decide the stuff for FOF wall pegging as it is. That is unless Transfer Line is involved which moves everything to the control sector linedefs instead...
Cutscene switch fix
Yet another fix for SUGOI, lol: apparently going from a final level's post-cutscene straight to a custom credits cutscene gets the latter stuck forever in the first scene (because the game accidentally stops the cutscene responder from realising the custom credits cutscene is running). This branch of course makes a fix for that.

Wall collision fixes
Fixes included in this branch:
* A fix for a specific crash encountered in a SUGOI map (sound familiar?) caused by bouncing off a wall adjacent to a slope
* A fix for solid midtextures not accounting for Effect 3/Peg Midtexture properly (https://mb.srb2.org/showthread.php?t=41462)
* A fix for solid midtextures not accounting for texture y offsets properly for non-Lower Unpegged/Peg Midtextured midtextures
* A fix for solid midtextures not accounting for "infinite" repeats (Repeat Midtexture + no repeat count set)
* ~~A fix for Effect 4 on Polyobject First Line making that particular linedef's midtexture solid in addition to making planes visible - this is not wanted if you want a polyobject with both visible planes and full intangibility.~~ Apparently they never did this anyway, don't mind me \o/

Fixed new new spriteframe angle
@Nev3r helped me discover a crash caused by NAMEcLcR not loading patches into every angle lump slot. This is the smallest possible change that fixes the crash.
This is a one line change exclusively modifying an edge case for a feature which isn't available in public builds. Therefore, it SHOULD require (almost) zero code review, and I would've committed directly to master if I had the ability to do that (and the desire to disregard ettiquette). Please help me out here.

Climbing shit 2 electric boogaloo: an adventure in how much toast hates how the ogl renderer was implemented
Fixed Knuckles being able to climb in space in OpenGL.
Using the last-touched line instead of R_IsPointInSubsector because FLOAT_TO_FIXED is bad in P_ functions
To understand the original problem: look at AjustSegs(void) in hw_bsp.c. It reallocates the vetex_t pointers for lines as POLYVERTEX_T pointers, and of COURSE things are gonna get wacky when you're casting pointers.
This merge request is into master because it's a bug that's IN master and must never reach the public because of how bad it is
