The last build had a nasty bug in it that would interfere with the timing of many spells.
This also fixes compatibility with the current (du jour) builds of WorldGuard.
- Some fixes to work with latest WorldGuard/WorldEdit
- Fix bug from 7.1.16 that makes construction spells take longer to build
- Tone down particles on shell and blob because apparently Mojang doesn't like fixing things they broke. But hey, pandas, amirite?
- Fix some issues with strength (damage multipliers)
