Draw fixes

Just fixed some drawing stuff, nothing big.

Tether fix

better project handling on spatial tether
removed redundant find free grid calls from many chronomancy teleports

removed redundant code from many chronomancy teleports

Small fixes

Finishing up on small known bugs (we are in beta! yay!)
* Scrolling a List or TreeList that takes up less place than provided used to result is weird shifting-jumps. Now it stays firmly in place.
* Scrollbars on List/TreeList used to not start from the very top. Now they do.
* util.scroll and util.bound converted to use math.min/math.max, as it doesn't trigger JIT branch perdiction and results in less performance loss. Also looks cleaner.
* Apprentice task now closes the damn item selection dialog!

Added an option to not use tilesets, for very crapper GPUs/Drivers

Tooltip improvements

Zip-zapping now actually gives you time to read and doesn't depend on frame rate.
Also TextzoneList can now zip-zap, too! (And does, in some dialogs).

Small fixes

Fixed resize of birth screen throwing errors.

Swl failsafe

put a 500 turn counter on the SWQ, if she doesn't have a target by the time it hits zero she targets the player and starts digging

How horrible.

Chrono tweaks

more chronomancy talent balance
updated some talents to use callbackOnTeleport
added type and subtype to water tiles where it was missing
added a bypass for trap avoidance for 'beneficial traps' such as the player's own wormholes
made blighted and magewearrior staff egos not show up more often than other greater egos
