Animated sky support
What it says on the tin: skies can be animated textures now. Just set them up as normal animated textures (keeping in mind the starting texture still has to comply with the SKYn/SKYnn/SKYnnn naming format) and hey presto, your sky animates.

* flips the sprite ala MFE_VERTICALFLIP except you don't need to flip the direction of gravity for the object just to draw upside down
* stacks properly with reverse gravity
* That hacky anti-NiGHTS-deaxisment code I commented out because I thought it was visual only? Reimplemented in a way that is both more and less hacky. It's identical in result to the original code, but takes a roundabout method to get there.
* Sprite references for SUPE, SUPZ and NDRL are removed because they are now unused.
* Helper's flashing conditional is restructured to do less flag swapping.
* The check for super setting FF_FULLBRIGHT is limited to MAXTRANSLATIONS now, and also correctly takes into account MAXSKINCOLORS == SKINCOLOR_SUPERSILVER1.
* NiGHTS collision bounds aren't hardcoded anymore.
* NiGHTS link will never display when leaving stage.
* Slightly tweaked rules for the supercolor setting when doing a NiGHTS transformation, but only meaningful for setting FF_FULLBRIGHT.
* Several new supercolours.
- SKINCOLOR_SUPERSILVER1-5 (for fun) - "Silver"
- SKINCOLOR_SUPERPERIDOT1-5 (nyeheheh) - "Peridot"
- SKINCOLOR_SUPERCYAN1-5 (for fun) - "Cyan"
- SKINCOLOR_SUPERPURPLE1-5 (for fun) - "Purple"
- SKINCOLOR_SUPERRUST1-5 (mecha/metal sonic) - "Rust"
- SKINCOLOR_SUPERTAN1-5 (shadow/silver the hedgehog) - "Tan"
* SKINCOLOR_SUPER1-5 renamed to SKINCOLOR_SUPERGOLD1-5, one index for darkest is changed - "Gold"
* SKINCOLOR_TSUPER1-5 renamed to SKINCOLOR_SUPERORANGE1-5, ported properly to the new palette - "Orange"
* SKINCOLOR_KSUPER1-5 renamed to SKINCOLOR_SUPERRED1-5, ported properly to the new palette - "Red"
* new S_SKIN attribute - supercolor - uses an entirely different function to get the names (R_GetSuperColorByName instead of R_GetColorByName)
* a fun little secret - typing "god on" in the console whilst super makes the player hyper (visual only, no sparkles - just rainbow flash) - can be removed if no fun is allowed
* Electric sparks coming off entire body instead of bubbles coming out mouth
* Different sounds.
* Different icons.
These sprites are currently local only, but I'll be doing a lot of asset updating this evening since Rob asked me to so it won't be long until you can get them.
xorshift* PRNG
This needs testing to ensure I didn't mess anything up switching function names around.
Our PRNG sucks. This is probably obvious. I wish I had known better at the time I implemented it, but oh well.
The replacement is an xorshift* PRNG variant with period 2^32 - 1 (meaning that the PRNG state will loop after four billion calls ... that's not likely to happen), versus the old PRNG's period of about 2^22 (?). The output is also much more random and less predictable; the old PRNG would fall into a predictable loop of output after about 4000 numbers were generated, which isn't much.
The PRNG here also outputs numbers as fixed point from [0,1) (that's 0 to FRACUNIT-1, in other words) instead of single bytes at a time. This makes it much easier to calculate things for, say, P_RandomRange and P_RandomKey. A new macro, P_RandomChance(p), is now in use that returns true _p_ percent of the time, where _p_ is a fixed_t probability from 0 (0%) to FRACUNIT (100%).
This doesn't affect netgames at all; the code for seed saving and restoring is identical (aside from a check to prevent seed being set to 0, which breaks xorshift PRNGs). Demos break, but A: _duh_ and B: they're already broken by all the changes to physics to accommodate slopes.
P_Random is deprecated in Lua, as the function was renamed to P_RandomByte. Aside from that, nothing special.

P_RandomChance is now a macro for something that should happen a
certain percentage of time.
P_SignedRandom was moved to a macro. Nobody cared.

the screen texture does not need an alpha channel.
the fact that it had one made OGL copy the topmost pixel of the screen texture's alpha channel.
which, naturally results in the screen becoming partially transparent and letting you see the working texture in the background.
Reduced palette
You guys should know what this is by now. If you don't, you really need to catch up. =P
We should check with toaster and others involved to check this thing is actually ready to go though, the number of changes to the palette itself over the last year has been absurd.

It's a lot nicer in general, honestly. I think a couple bugs with custom monitors respawning got fixed in the process.
Note that a monitorgfx.wad is needed if you want to see things besides <!>s for monitors, due to graphic changes.
