Various Task Improvements (Patch, Strip, Recompile)

[shartte]

This combines various task improvements aimed at reducing task inputs and thus the work that up-to-date checks and build-cache have to do.

• Use DiffPatches ability to apply patches directly from ZIP-Files and use the NeoForm artifact as the source directly
• Minor cleanup use try-with-resources in Strip
• Don't use doLast in RecompileSources and instead move it in to the Task action
• Don't cache ArtifactFromOutput since it's just a file copy (see Gradles own Copy task for similar reasoning on their part)
