Use NIO instead of ZipUtil (#513)

Browse source 
* Use nio for zip utils

* Make tests work

* Please work

* Fix some issues with tests

* Fix more issues with tests

* NIOZipUtils -> ZipUtils

* Resolve Juuxel's reviews

* Use our own FS utils

* Improve error handling, add loom Pair

* Add Unit tests + fixes
