Add all open files to task

[pzelnip]

Oftentimes while working on a task I forget to explicitly add a file to the current active task. It'd be nice to have a button (say beside the "Activate Task" & "Open All Files" button on the task menu to "Add all currently open files to this task".

This would allow me to (right before changing to another task) to quickly make sure everything is added before I close everything and switch to a new task (currently, assuming I remember to do so, I manually flick through each open file and click the "Add File to Active Task" button, which is tedious).
