New version 0.4.1 out.

As yrannadx confirmed the necessity of cell modem to be online, I added some check and an infinite loop until first connectiion, then the switch starts. This may be canceled via command-line 'sim-switcher cancel'.

changelog
Added direct call of editor for config file without switching code (first start).
Added online check before starting the switch (some adapter needs online status), may be deactivated.
Added new param (stop) to interactively break/cancel a hanging switch (due to not being online).
