[TYPO3-core] FYI #12406: Bug / Code cleanup: Scheduler: Minor cleanups in BE module

[Francois Suter]

The attached patch has been committed to trunk in revision 6303

Type: Bugfix / Code cleanup

Bugtracker references:
http://bugs.typo3.org/view.php?id=12406

Branches:
Trunk

Problems & solutions:
The attached patch solved the following issues:

- in the list view, running tasks appeared disabled if their current run 
was their last run. An improved check makes sure the task still appears 
as running (it will appear disabled when it has finished running).
- in two places, the code used a hard-coded error status instead of 
t3lib_FlashMessage::ERROR
- a couple of variable initializations were added where appropriate
- image clear.gif was removed, as it is unused (using svn delete)

Cheers
