Git plugin?

Can we get support for github so we can backup the system to a remote git repo? This would be awesome as it would allow versioning and backups. We should be able to push / sync the entire system and or individual notbooks etc. Retoring should also be eay. If something happens and we have to pull a old copy of a spefic file this should be easy to do with the history and gits native versioning. Or, if we have a drive failure we simple get that resovled and reinstall siyuan and point it to the git repo and restore the entire thing. Support for braching woujld be nice so we can have the entire system on the main branch and then indivdual notebooks in sub branches.
