Fix inability to run in background on Mavericks.

Add MacActivity class for handling starting and
stopping of "activities" through NSProcessInfo.
This allows CopyQ to continue running in the
background on OS X 10.9.
update TODO list.
Add MacTimer to allow setting tolerance.

Mavericks has the ability to set a "tolerance"
on an NSTimer, which allows the OS to more
efficiently schedule timers. This adds a class
which allows CopyQ to make use of that.
