New gameplay option to auto-validate the default target; thus requiring only one keypress to fire a talent

Made Reshape W/A truly idempotent and also it now autoupdates through normal means and not horrible hacks.

Makes known traps and event terrain effects remembered on the map and minimap (with distinct colors for each).
Fix some bugs that was causing the nice tiler to overwrite modified grids for some events and make overlapping events behave nicely.
Adds "Lua inspect [Trap]" to the map menu in debug mode.

Note: May need new particle effects to make remembered area effects out of LOS look better.

DarkGod, space kerns with some letters. Kerns heavily. SDL_TTF also
sucks heavily enough to not tell us that. If you could change font:draw
so that it collected all the text in the line (of one style at least)
and rendered it at once, thus preserving kerning, that'd be wonderful.
Again, when we move to atlasi, this is going to become a pain again.
Probably will need something which can return full character metrics.

Fixed the oddity with being blinded (well, worked around it). Also cleaned shader code up while I'm at it.

(esp now that splitLines is kinda irrelevant since we use font:draw)

Fixed textzones being too spacious/cut off sometimes as a consequence (when they have many tall letters).

Ice Storm stays in place after the source is dead (just in case); map effects actually check for duration set to 0

Symmetry screwed with equipping two rings consequentially in no particular slot, so I changed to to be less symmetric (as it used to be).

NPC's will tell allies about enemies at slightly greater range (affected by game difficulty) and guesses for the position of unseen hostiles will be a bit better.
