A bunch of bug fixes with this one, working my way towards clearing as many of the reported issues as possible by the end of the month.

BUGS AND CRASHES::
- Spawners will now spawn in wide open locations so that they arn't crammed into corners or hallways.
- Spawners will 'close' the tiles around them so they cant get surrounded by stuff like fire shrooms.
- Player can no longer sell traps, allowing him to exceed the trap cap.
- On discord someone reported 'warping' through a timed gate. I wasn't able to replicate it but I've changed the gates so they won't close if someone is standing on them. My only guess is that you walked into it at the same time it closed maybe?
- Fixed: timed gate message doesn't show up if another message occurs at same time when entering a level.
- Fixed: if a terrain tile is placed where you are standing, it was taking a turn before you became unstable.
- Baby slimes will now 'float' on water (they were to small to see).
- Fixed: hellfire on enemies in water was causing Los to be lost due to steam and the hellfire didn't hit everyone it should have.
- Starvation damage will no longer free you from webs / nets
- Constrict will now block stair use, even if you are constricted on the same turn you try to use the stairs.
- Fixed 'available talents' list so that it resets its position when starting a new game.
- goto-stairs keys should prioritize the main dungeon rather than the branches.
- Putting on a helm of telepathy (or other item) will now instantly reveal the map, rather than taking a turn.

INTERFACE:
- Added a proper message queue to handle the bug above where messages would be 'overwritten' if two popped up at same time. Now any number of messages can be sent to the player and they will simply open one after another.
- Monsters will now show up as red dots on the mini map if they are in your LoS.
- You can now mouse over to get a desc of monsters on the mini map.
- Most text menus will now allow 'accept' and 'escape' buttons to trigger their buttons if its a simple yes/no question.

MISC:
- Monster glyph rooms will no longer spawn on the first floor of the dungeon.
- Changed ring of sustenance to unenchantable since there is currently no bonus to enchanting it.
