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
HWR_DrawFill support for V_NOSCALESTART
This fixes the console selection highlighting being wrongly positioned and sized for OpenGL.

Sprite2 changes
Some stuff!
* Lua access to sprite2.
* Introducing new Lua-exclusive function, P_IsValidSprite2(mo, spr2). Basically just a wrapper for (((skin_t *)mobj->skin)->sprites[spr2].numframes > 0), useful for creating custom sprite2 defaulting functions since hooking into P_GetMobjSprite2 wouldn't be worth it.
* FF_ANIMATE support for sprite2s. The var2 of the state works identically to normal FF_ANIMATE, but var1 is completely disregarded - it just runs all of the frames available to that one sprite2 animation set.
* As a result, a bunch of states which were either not previously animatable or had animated at constant speed now get animation without state changes.
* P_SetMobjState now supports sprite2 defaulting like P_SetPlayerMobjState does.
