Title: Add usage message to Roxie

Adding help function to Roxie server and standalone binaries.

Examples:

Calling the server binary directly:

Roxie Server: Starts the Roxie service or executes a one-off query.

Service:
topology=[XML-file]	: Reads Roxie topology (deafult RoxieTopology.xml)
port=[integer]	: Network port (default 9876)

One-off query:
loadWorkunit=[so|dll]	: Load and execute shared library
-[xml|csv|raw]	: Output format (default ascii)

Generic:
daliServers=[host1,...]	: List of Dali servers to use
tracelevel=[integer]	: Amount of information to dump on logs
stdlog=[boolean]	: Standard log format (based on tracelevel)
logfile=[format]	: Outputs to logfile, rather than stdout

Testing:
selftest [test1 ...]	: Unit tests to run (default is all)

Or calling a compiled Roxie binary:

$ ./dynamic help
Usage: dynamic [options]

Options:
daliServers=[host1,...]	: List of Dali servers to use
tracelevel=[integer]	: Amount of information to dump on logs
stdlog=[boolean]	: Standard log format (based on tracelevel)
logfile=[format]	: Outputs to logfile, rather than stdout

Also changed ```-selftest``` to ```selftest``` for consistency. This has no external visibility.
