#259 Simple Schedule in GUI

[David Baxendale]

It would be nice to have a simple job schedule in the GUI, so that you can drag and drop various backup jobs into a Schedule Window for Areca to run. Once the user has placed the jobs in the Schedule Window, upon selecting a RUN button, Areca would then proceed to run the jobs sequentially.

I know this can be done via the command line, but it would be a nice feature to do this within the GUI.
