chore: Use local copies of morphe-patcher and morphe-library if available

[wchill]

This change makes it so that we don't need to fiddle with publishing to local maven + changing version numbers when testing changes to library or patcher. If those two repos are not checked out, then it will continue to pull the JARs from the defined Maven repositories; else Gradle will rebuild all the modified projects as needed.

Go ahead and merge this on my behalf if things look good, this was one of my biggest issues with testing changes in morphe-patcher

I've been able to make changes without changing version numbers, since mavenLocal() is pulled in before the remote repos.

But, this will make things easier than constantly publishing to maven local or if forgetting to run publish.
