v2.1.0 with several additions and colour improvements

I've made several improvements.  Would appreciate people's testing and feedback.

v2.1.0 (11 April 2014)

* Upload process now displays number of files in the queue (eg. "1 of 52")
* Output now clearly indicates if it's running in --list mode
* Added more ANSI colours to output
* Added --debug option which provides much more verbose output
* Added --help option which displays the readme.md file
* Added --version option which displays the version of the script and exits
* Internal: ANSI colours are now expressed through simple HTML-like tags such as <red>, <white> etc.
* Internal: git & console commands are now run from a central function to reduce code repetition and potential bugs
* Fictional: phploy now makes your coffee during a long deployment

**Note:** There a couple of outstanding bugs (not my code) I discovered when making these changes, these are noted inside the code.
