Add Stopwatch functionality about mycroft-timer

[jrwarwick]

I went ahead with a separate skill: https://github.com/jrwarwick/mark-time-skill.git
If/when it seems prudent or desirable to improve and move the functionality into timer skill, I would invite and prefer that. But for now I'll hack on my edition.

Hey Justin,

Thanks for the feature suggestion and clear articulation. I think this would be a great addition to the Timer Skill.

Do you think the vocab of "timer" vs "timing" is different enough to distinguish the two modes?
Eg currently "begin timer" prompts the user for a timer length and then starts counting down.
My understanding is that this addition would use "begin timing" and immediately start counting up.

It feels right to me at first glance.

Hello Kris, I had not given the specific vocab full thought, but your suggestion makes sense and I agree that as you say, it does "feel right".
So I suppose a typical usage would be:
"Hey Mycroft, begin timing."
"Timing started"
human performs some activities, then:
"Hey Mycroft, stop timing."
"Timing stopped. Elapsed time was 3 minutes and 42 seconds."
A "pause timing" and "resume timing" would be good. And I suppose also that, if user utters "begin timing" again before "stop timing" Mycroft should first say that a timing task is already in progress, report time so far, and then ask for confirmation for a reset and restart.
