Fixed routed units contributing dice at the start of a battle even though they shouldn't.

Activated the "hide pointer" option on the order areas to better hide which order players choose.

- removed now unused call to raise walls when scanning for a battle

- changed dice wall logic to keep walls up as long as there are dice being rolled in some way

optimized material collection (courtesy of Ember):
- only checking for seated players
- output in player color

regarding ui for units on the battle board:
- removed "return" button (not really needed as far as I can tell)
- greyed out HP "button", since it's just a display item

- fixed XmlLayout error for those who have the -log launch option active on TTS

- fixed dice walls after update

- changed the invisible walls that stop dice from flying off the battle boards so they only appear while the dice are rolled initially

- fixed bug that occurs when a dice is put bag into the bag and starts rolling
