ktc --version returns wrong version

The current version, as specified [here](https://github.com/timed-c/ktc/blob/master/src/main.ml#L7) is 1.1, but the version which is returned when running `ktc --version` is defined [here](https://github.com/timed-c/ktc/blob/master/lib/Ktc.pm#L6) as 1.0.0 and will therefore give the wrong output.
