whenjobs 0.6 released

whenjobs 0.6 fixes two out of three bugs mentioned previously, and fixes the bug Joe found in whenjobs --daemon-start (et al).

Changes:

• You can set multiple variables atomically, using:

  whenjobs --set cat=sushi food=fish
  

  The effect is that when-clauses are reevaluated only after all the variables have changed, rather than after each change as before.

• You can test the effect of setting variables, without setting them (or running jobs). The new --test option displays which jobs would run:

  $ whenjobs --test food=meat
  job$1
  job$5
  

• whenjobs --daemon-{start,restart,status} now all work as expected
• whenjobs --job-names lists job names of all loaded jobs, whether running or not.
