Enhancement: add support for Firefox OS on deploy tools

This pull request includes two things:

First: the "-v" parameter in deploy.sh in Cordova webOS case is in the wrong position and this affects Mac OS X

Second: I added support for bundling Firefox OS application manifest if you pass the -fxos or --firefoxos parameter. The file called manifest.webapp is used by Firefox OS much like appinfo.json is used by webOS.
