Additions

• Delete schematic effect - deletes a schematic (this can't be undone!)
• Forest effect - generates a forest in a region, with a specific tree species and density

Other (pretty boring) stuff

• Internally changes how versioning is done. Now only needs to be changed in the gradle build file, instead of in all three files where the version was included.

Full Changelog: 1.1.1...1.1.2
