Updated to support RimWorld 1.6!

Added some Mod Settings.
- You can now set Runecircle Recharge Rates.
- You can now set if Runecircles break on Invoking.

Quick update that adds some community suggested features.
- All Invoke Psycasts no longer require Line of Sight.
- All Invoke Psycasts have a range of 62.5, up from 42.5.
- Standard Runecircle Psyfocus Cost increased to 60%, up from 20%. They are no longer consumed on Invoke, but take 10 days to recharge.
- Greater Runecircle Psyfocus Cost increased to 90%, up from 55%. They are no longer consumed on Invoke, but take 15 days to recharge.

Then, a quick fix due to these changes.
- Slight change to Invoke: Isa, due to the fact that runes don't get consumed anymore. Obelisks now spawn on an adjacent tile if possible, so as to prevent crushing the Runecircle that spawned it.

Slight update to give Crude Runecircles unique textures.

Just a bunch of minor text fixes.
- Removed mentions of "spells", replacing them with "psycasts".
- Capitalized the usage of rune names.

Initial upload of the mod.
