Implement profiling about activitywatch-old

[ErikBjare]

I did a long-duration profiling (with very little user activity) which might be useful when optimizing and for comparing with future profilings. Here there was no weird 100% CPU core allocation bug.

         20459418 function calls (20482128 primitive calls) in 236.565 seconds

There was more but it seemed excessive to include. Future profilings should not include builtins.

Profiling is currently available via the profile.py script.

Closing for now.
