#316 support "failure action" for libtaskotron actions
Closed: Invalid Opened by tflink.

Currently, if any action in a task fails, execution stops. While this has made sense for us so far, it may not always make sense.

Modify/enhance formula syntax to support specifying a "failure action", keeping a sane default if it's not specified


To be a little more clear, a "failure action" would be one of:
* Ignore failure, keep on going
* Stop with CRASHED result
* Stop with FAILED result

We no longer have custom formulae, closing.
