Release Background Auto Save v0.9

[BryanChi]

first release

[X-Raym]

@BryanChi the way the loop is done here could be optimized:

https://github.com/ReaTeam/ReaScripts-Templates/blob/master/Templates/X-Raym_Background%20script%20-%20run%20action%20every%20X%20seconds.lua

Also, dont forget error message if ultraschall isnt present.

It also miss some basic backround stuff like reporting toggle button state :

Thanks for checking this, I've updated it. The other pull request is actually a different script, but I messed up the names when I uploaded and it's not letting me change them. This script should be 'Background auto save', which is a defering script, and the other one called 'Background Save', which is a one time save.

I'm closing it because I just realized it actually doesn't work...... sorry!
