Spindash dust
Charging a spindash kicks up dust, we all know this feature was dying to get in at some point. Bubble and flame forms of spin dust are included from FSonic, for underwater and elemental respectively.
Oh, and as a bonus I reorganised the spindash/spinning/other ability2 stuff code to look a bit neater and more organised.
New resources:
* MT_SPINDUST - the object
* S_SPINDUST1 to 4 - the normal form's states
* S_SPINDUST_BUBBLE1 to 4 - the bubble form's states
* S_SPINDUST_FIRE1 to 4 - the bubble form's states
* SPR_DUST - the normal form's sprite set (uses frames A to D, just pinch FSonic's sprites really)
* SPR_FPRT - the flame form's sprite set (frame A only)
SF_NOSPINDASHDUST disables spindash dust for a character

Multi-patch texture support for transparency AND translucency
Fixes the transparent bits of the multi-patch glass texture in THZ1 turning cyan when linedef types 900-908 are applied for translucency
See merge request !56
Zoom tube camera fix
Fixed a mistake where I accidentially allowed people to change the player angle whilst in a zoom tube when previously improving them.
See merge request !57
Smoother ropes and zoom tubes
Makes rope hangs and zoom tubes suck less. Specifically, they handle corners (and vertical height changes, ala sloped rope hangs) a LOT nicer. Ported from internal.
See merge request !139
As LJSonic has pointed out, there's no need for a for loop in either case; just use sector->floorpic/ceilingpic as a levelflats index directly
(Besides, if that was to stop any out-of-bounds indexes being used, that's hardly the way to do it anyway)
TEXTURES additions
Some new features and fixes for textures and the TEXTURES lump:
* Flipping of individual patches used by textures is now supported, both horizontally and vertically. The formatting for doing so in TEXTURES should match that of ZDoom's:
```
WallTexture EXAMPLE, 128, 128
{
Patch TEST, 0, 0
Patch TEST, 64, 0
{
FlipX
}
Patch TEST, 0, 64
{
FlipY
}
Patch TEST, 64, 64
{
FlipX
FlipY
}
}
```
(in other words you need { and } below the Patch you want to flip, containing FlipX if you want horizontal flipping or FlipY if you want vertical flipping... or both, if you want both!)
* Negative patch y-offsets should now work properly for multi-patch textures or single-patch textures with no holes.

SDL2 i_video.c code cleanup
Made some code look a bit neater, removed the need for some SDL2STUBs Fury placed, vid_info console command actually kind of has a use again, etc
See merge request !138
Fix ceiling springs thrusting themselves down in midair on touch
What the title says. I blame MFE_ONGROUND for being stupid, but for now I made it behave a bit better with flipped items at least.
See merge request !140
*Added FLIPX/FLIPY support for multi-patch textures and single-patch textures without holes
*Added FLIPY support for single-patch textures with holes; I'll sort FLIPX support out later
To re-enable support for the above, uncomment the define HAVE_LUA_SEGS line in lua_script.h. Plain bbox userdata stuff is not disabled (though currently it's not used anyway)
* Cleaner A_ParticleSpawn code.
* Removed several hacks with Mario blocks, and corrected a mistaken assumption with when the FOF's thinker is being applied.
* Made the flashing of T_LaserFlash even less obnoxious.
Turns out sdl12's version of this function only did stuff for DC/GP2X ports; support for them have been cut out for SDL2, so for now let's just not use the function at all
I'm convinced there's going to be some stupid side effects from doing this, but it's the quickest way I can fix the polyobj planes not all appearing anyway
