movejs - Rename/Move CJS module(s) and update all affected requires

Package root is intelligently detected Content of eventual node_modules (external dependencies) folder is not affected All files as ignored by .gitignore rules are not touched (it is assumed they're most likely generated files, which will automatically be fixed by regeneration). Constraints: Moved module must reside in some package otherwise root of a system is perceived as a root of a package, and operation is aborted (to not proceed with whole system files search for affected modules) Modules can be moved only within a scope of same package. For obvious reasons move across different packages will fail
