Dont fail if one Task file throws an exception

[turtle0x1]

If you have a ...Task.php file that throws an exception, none of the jobs run.

Ive been stung by this in past and without being able to call the task pragmatically (or atleast I cant work out how) you have to-do extra work to make sure this isn't preventing your jobs from being run.

Could try to submit a PR but would need some pointers 😄

Crunz could do some try/catch magic, but it's tricky, it will be better to handle this situation in script.
