Add an option to activate a task

[ka1zersose]

Sometimes there are user stories which consist of many tasks, which is handled by different developers. In that case, i would like to have a "task #: " in my commit text box, however right now there is no possibility to set the task as active, in the same way you set a user story.

I propose change settings dialog like this:

and add support for activate task similar to activate work item.
Commit message will be: task #1105: do something

@janotav What do you think? If it's OK, I will implement it.

@kovalcikr Go ahead :-)
