Description

This PR makes changes to allow faster building and mining in Sandbox mode.
This makes sense to me because Sandbox mode should be all about building stuff.

Although PlacementCommon.as was changed to not check for rules tag "faster building" anymore, I added it back in and added the tag to Sandbox_Rules.as.

I noticed BuilderLogic.as would list animations "chop_fast" and "strike_fast" even though they aren't listed in Builder.cfg.
So I added them to Builder.cfg, reducing the animation time from 12 ticks to 8 ticks each.
The faster version is applied when rules has tag "faster mining", which is also set to Sandbox_Rules.as.

If players would prefer the normal speed, maybe we can think about adding a player-based setting to allow both, either in the menu or within the game-world (as a button in buildershop maybe).

Tested in offline and online, works as intended.
