[#293] Mob timer should work anywhere on the system

[maciej-stanuch]

I've added a check for git availability in getMobTimerRoom method to allow it to work anywhere in the system.

So, now the behaviour is like this:

• If git repository -> works as it worked before
• If not a git repository -> use the room name from MOB_TIMER_ROOM

---

I wonder if the code, especially mob.go file, shouldn't be somehow split into smaller files? It's slightly difficult to work with.
I have not much experience in Go and maybe that's not a good idea to separate all that stuff? I feel like it would make it easier to test it at least.

We could even write a test for this. As part of the testbed, there's a directory that is not a git repo. We could switch to that and call the main method with mob timer 0 and verify that we get a specific output in the console. We should change the configuration of the notify command so that no sound output will be generated when running this test.

The issue with long files is discussed at #296

Will do, I haven't much free time recently to finish it up properly
