Support update from Github about oik

[bobbingwide]

Need to look at https://github.com/afragen/github-updater 's solution

If the local plugin is a Git repository... which is already detectable... then shouldn’t it be possible to simply perform a pull? It assumes the server has the authority to run git stuff.

I'll write some test code in oik-batch to do some git capability checking and display a box in the oik options page using a similar technique to that which oik-css uses.

Those logic to support update from a Github repo was added in
bobbingwide/oik-batch#34.
A new issue has been raised to allow a component to be added from a github repo.
bobbingwide/oik-batch#35.

As previously stated an update from GitHub solution was implemented in bobbingwide/oik-batch#34. The other issue ( 35 ) hasn’t been addressed.

I'm going to close this issue in oik as the solution is available in oik-batch.
Also, wordpress.org may not like this logic being included.
