Also detect orted failed-to-start by setting timeout on launch. Currently only used in TM launcher. Neither detection is enabled by default, but are only active if heartrate is set and/or launch timeout is set. Exception for SLURM as orted failure is always detected and reported. More info to come on devel list. This commit was SVN r18555.
