Gpii-119: Updated reference to infusion repository and modified GPII code accordingly

I updated the reference to the fluid-infusion project, so that it now includes the work done on transformaitons, as well as containing the definitions of escaped get/set configs which were currently defined in multiple areas of the GPII code.

Note that the tests from the XML settingshandler that have been removed are due to them having been moved to the trnasformation framework tests, and likewise - the transformation related code from the settingshandler and utils that have been moved is because they now exist in the transformation framework of fluid infusion
