Treat all args after the script name as script args

This fixes CapserJS which builds a command line like this:
phantomjs bin/bootstrap.js --casper-path=~/capserjs --cli

That works on Phantom 1.6 but not on master due to the qcommandline
port.

Fix by extending qcommandlne to take a ParameterFence flag which causes
it to treat any options after a parameter as arguments. Switch
"scriptname" to use that so the 1.6 behaviour is restored.
