[PATCH 0 of 1] Conflicting short option -t for patchbomb and tasks.

[Johan Samyn]

Both extensions currently have a short option '-t'.
Patchbomb for specifying the recipient(s), tasks for supplying a task to the email command.
As the one by patchbomb itself rules imho, I removed the option from the tasks.py source, as it has also a long '--task' form as a possibility.
This was causing trouble in TortoiseHg too btw.
