snap-packaging for gitea (#2568)

* Modify tbraeutigam/gogs-snap for gitea * Fix building on 16.04 (manually build go-bindata). -> add _source.tar.bz2 to .gitignore (used by snapcraft cleanbuild) * Streamline Snap packaging: - Take advantage of install-hooks (snapd 2.27) - Use snapctl configuration storage for unchanging values * Move to using Snap Hooks for configuration * Missed re-adding daemon statement * Fix two warnings from Codacy.

+summary:  Gitea - A painless self-hosted Git service
+description: |
+  The goal of this project is to make the easiest, fastest, and most painless
+  way of setting up a self-hosted Git service. With Go, this can be done with
+  an independent binary distribution across ALL platforms that Go supports,
+  including Linux, Mac OS X, Windows and ARM.
