Fixes long opt parsing as '--port' and '--bind-to' did not expect values.

Siminlar to the syntax for short options, for which a colon (':') indicates
that the option must be followed by an parameter, for long options the getopt
parser expects an equal-sign ('=') as a suffix in the specification of a para-
meter. Otherwise the value of 'arg' of a corresponding 'opt' is a zero-length
string. In this case, a call to 'int(arg)' will fail with an exception.

Appending '=' to the options 'port' and 'bind-to' resolves this issue.
