Brought logging to cliresms

So far, the -v switch was not used. Now we use it to make it use the logging module.
Debugging an exception in config parsing

It will now print the line if it failed to parse an alias line. It might
be worth it to do that for the whole parsing process though.
Ignore comments in config file
Added logging for parsing the config file

Unfortunately, some whitespace clutter has crept in.
Enabled config to contain group definitions, i.e. alias foo bar baz

That was a nice feature of o2sms. You could define
alais beerpeople greg 1234 bob
and write to both of them easily
That was currently not supported. Now it should work.

This is based on work done by Tobias Mueller. I just added parsing
using regexes to allow for the parsing to be a bit more flexible and
resilient to slightly malformed but otherwise correct lines.
Brougth more logging to the actual messages that are sent

It doesn't send messages > 160 characters so I am investigating here.
Have 'split' default to true to enable sending longer messages

and warn if message is longer than the threshold so that the user knows that the message will be truncated.
