MapScript colorObj SWIG/PHP alignment and methods with alpha

Changes in the SWIG bindings:
- add the methods setRGBA() and toHexWithAlpha()
- extend the method setHex() to accept #rrggbbaa hex values

Changes in the PHP bindings:
- add the methods setRGBA() and toHexWithAlpha()
- adds the methods toHex() and setHex() which were already in the SWIG bindings
