Adds a "pause time" option when idle

[Azn9]

Currently the only options are

• Keep tracking the time (ie. if I work 1h, idle 1h, then work 1h, it counts 3h)
• Reset the time (ie. if I work 1h, idle 1h, then work 1h, it counts 1h)

A "pause" option should be available (ie. if I work 1h, idle 1h, then work 1h, it counts 2h)

Right now there is only a checkbox on the options, it would be better to replace it with a dropdown menu.

Also, adding the ability to choose this behavior per project would be nice.
