Support for i3blocks signalling and configurable seconds

Hi Andrea,

I use i3 as WM, and specifically i3blocks as status bar. i3blocks has the nice ability that a status update can be triggered by using unix process signals. This way, the current status has not to be polled constantly, especially not when not even a pomodori session is running.

So I implemented this signalling, based on environment variables. As you suggested in the code to use environment variables anyway, e.g. to configure the seconds, I decided to go for it and implemented the change for the seconds as well. This was actually a bigger change as you had 25 minutes hard-coded in the console output.

I also changed the default behaviour of pom. Without an action, now pom ls is invoked.

Things to consider:

This can be used for any kind of process signalling, both process name and signal is configurable now.
If the environment variables are not set, then nothing happens, so it is fully backwards compatible.
As of now, pkill is used to send the signal, so this is a dependency if the feature is to be used.
Untested on Mac, on Windows it will certainly not work (but should also not hurt).
At least with my blocklet that shows the status, it is not clear that a pomodori-session is finished (probably I could check if the time in todo.txt.tmux is 0:00). So the last status with my task and time 0:00 remains on the status bar. I, however, like it this way, as I see then that the time is over. It gets removed when an update is triggered and the todo.txt.tmux file is not modified since more than 5 seconds. So I simply call todo.sh pom once to get it finally removed. That's why pom also signals when invoked (and then every second while the timer is running).

Hope you like it.

Cheers,

Kai
