Run fstack on evolution, (while it is sleeping), and fstack will print a stack
trace and then hang. Most likely reason is a problem when the ProcTasks observer
is removed from the process. Since the deletedFrom method is not called.

Ran gnu styler.
Used procAttachedObserver rather than procTasksObserver
(addOptions): Added information about ALL logging option.
(removeObservers): Changed to use the process not the task.
(requestDeletes): Added, removes the attachedObserver from all of the ta
(storeTasks): Used integer tid as key rather than string tid as key so s
orted in ascending trace number order. Fixes issue with traces printing
d orders like 21 22 3021 42.
