Some wand template updates
Store wand properties under a single compound tag.

This will be a breaking change for all wands. Sorry!
Add haste property to wands
Add "time" spell variant for toggling day/night
Re-work material overrides so spell variants are set with them up front.
Add y-offset parameter to construct, for sandblast.
Add code to port old wands.
Implement configurable block populator for wand chests.
Typo fixes
Bump version number since this is a pretty major change.
