Option for not creating backup

[andia89]

I personally don't want to create backups all the time since I don't care about the original icons and don't want to clutter my harddisk with unnecessary files too much.

How about an option that disables the possibility to create backups? (And one the cleans already exisiting ones, maybe)

I will add the option for not creating a backup to the new config.json file that i've added recently :)
And i will add an argument to clean the old backups

This should land next weekend! i'm improving the base code of Hardcode-Tray and make it more easier to create new plugins for it :)
