v0.9.0.
Fixed #run code, now task funciton 'fn' gets a 'done' function as the
1st argument, if 'times' argument is passed to #run; this function
should be called when task is considered finished, to mantain the
correct number of task executions.
Fixed tests for #run.
Changed 'times' property for task entry to 'left'.
