Theme: Less frequent Git updates notifications

[adiastra]

Mabe have us be able to choose the number of days before checking for git updates.

maybe enough to decide what to do with regard to the changelog and if you think you need it? Also, you always see the latest...so, honestly, in my opinion this is not an issue...

Probably adding a feature when you could manually check for Git updates and also do force upgrade would a convenient thing..

.. will see..

This was one of the reasons i wanted to add manually check for updates and a force update #725

1. theme-update.sh now accepts params to install either beta(git), release(latest) or specific release release:XX.XX. You can run ./theme-update.sh --help to get the help:

Authentic Theme update script
Usage:  ./theme-update.sh { [-beta] | [-release] | [-release:number] }
[root@debug authentic-theme]# 

For example to install release with version 18.45 just run:

./theme-update.sh -release:18.45

2. I have removed the button from Update Notice and added it to Theme Settings. Now user can choose if to install development or latest release version.
