Allow developer set the site where to download game resource.(0.9 branch) (#442)

* Add mirrors util and mirror configuration

* Fix NPE in MirrorConfiguration;
Add constants in Constants;
Rename Mirrors.java to MirrorUtil.java

* Bump gradle nightly version

* Apply mirror to download assets.
Need fix settings in LoomRepositoryPlugin.java

* Fix MojangMappingsSpec having the same hash version for each mc version.

I dont think this would be a real cause for concern as the jar would have had the mc version in it anyway.

* Revert "Fix MojangMappingsSpec having the same hash version for each mc version."

This reverts commit 61fa4d9f

* Remove MirrorConfiguration and move to MirrorUtil

* StyleCheck.

* Fix "IllegalStateException: The root project is not yet available for build."

* Remove some of the extra content.
