Slope fixes
This branch fixes the following slope-related physics and rendering bugs:
* Rings in multiplayer stages respawning inside slopes (even despite being able to spawn ABOVE them on map load)
* Player starts spawning players inside slopes
* Elemental flame trails not appearing if a player spindashes UP a slope; see issue #21
* Dying players "jumping" off slopes to the side if they were previously standing on one
* Some issues with FOF slope rendering
* Various issues with sprites displaying through walls adjacent to slopes
Other features added:
* Objectplace now supports slopes (this is Inuyasha's doing)
* Automap in DEVMODE now supports slopes (my doing)
Just making this merge request now rather than later, ~~in case I decide not to make any more fixes for the time being~~ (this branch doesn't seem to want to die lol), and so we can get these merged in as soon as the code's all been checked over.
See merge request !50
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.

Objectplace reallocates the mapthings list to add one more mapthing. By itself there's no problem with this.
But, mobj->spawnpoint is a pointer to the mapthing's location in the mapthings list.
So by reallocating the mapthings list, all references to mobj->spawnpoints point to freed memory.
... Oops.
Now when objectplace reallocates the mapthings list it actually corrects the locations of all mobj's spawnpoints to point to the new list.
Hooray, you can use NiGHTS objectplace again if you really want to.
Access the benefits of -debug, console devmode, and a complete gamedata.dat (all secrets unlocked) all in one go.
Moved "#if 0" and "#if 1" to "#ifdef DEVMODE" so the existance of this cheat and MD5 validation and all that can be toggled in one place too.
