Separate into scriptrunner and Iconification modules

[ralberth]

Moving an off-topic idea from Issue #3 over here as a new feature request:

The only way to improve this significantly now, would be the possibility to have different slots for displaying more icons at once. But that's probably a huge and time consuming effort. Off course other modules could benefit greatly from that by using ScriptScheduler.

My head's just spinning now. If you do want to put more effort into this, it might actually be a good idea to split ScriptScheduler into two modules:

1. ScriptScheduler, which handles the scheduled scripts but no icons itself, and
2. (maybe) Iconification for handling icon notifications

Thanks for doing all that work and considering it.
