Introducing the WPS tokenizer !

Browse source 
When a WPS file is loaded, it is parsed to an array of tokens, which allows more efficient displaying. More info on the tracker entry : FS #6862.
The parsing code is completely independant and is all in wps_parser.c. The displaying part stays in gwps-common.c.
Debugging code is provided (with the right ifdefs) and is disabled by default.
Overall, the code should be easier to read and maintain. Adding new WPS tags is made quite trivial.
