Some language correction and function handling

I more or less copied the language from i3-wm as it was more correct.
Also converted `print()` into `installation.log()` so that we can get some color control and end up in the debug log.
Finally, I added a try/except to handle potential crashes and return return values, since otherwise this would happen every run:
