refs #207, renamed CValueMap to CIndexVariantMap.

* The map will be used with CSimulaorInfo to transfer a variable number of setting information about the flight simulator. It is being used, because it is already DBus and tupel compliant. The new name better fits its purpose.
* Add == operator for CIndexVariantMap (ambiguity error with tupels)
