Invalid switch causes an unhandled exception

[gcorrall]

Giving an invalid switch to powerjoular on the command line raises an unhandled exception, displaying:

raised GNAT.COMMAND_LINE.INVALID_SWITCH : g-comlin.adb:756

I think handling the 'Invalid_Switch' exception to show an appropriate error message (or displaying the help text) would be preferable (e.g. https://www.adacore.com/gems/gem-52).

Thanks @gcorrall, I'll add handling these exceptions to the code.

Fixed in 45c3119.

I think this change may have broken things somewhat; running powerjoular (with no switch or any valid switch) now exits immediately (whilst an invalid switch does display an error message).

Indeed, I just pushed a hotfix, should fix it.
