Title: proposed fix to issue #247 (using mocha with node-inspector)

It is working well for me, following the path suggested by @visionmedia
Note: This does change the commandline operation of mocha by changing the --debug option's meaning
and instead, mapping the previous meaning to debug (no dashes)
