* Split shell command line into a list of arguments and optionally execute the command(s).
* Aims to emulate \c bash and friends.
*
* - Command nesting is possible with brackets [example: validateaddress(getnewaddress())]
* - Command nesting is possible with parenthesis; for example: validateaddress(getnewaddress())
* - Arguments are delimited with whitespace or comma
* - Extra whitespace at the beginning and end and between arguments will be ignored
* - Text can be "double" or 'single' quoted
