Refactor so we have only one definition map and ControlTypeAndPart

Until now we had multiple maps, each for a specific ControlType
(maPushButtonDefinitions for example) which had multiple parts
identified by the string.
To simplify matters, this changes that we have just one map for
a specific ControlType and ControlPart which are identified by
ControlTypeAndPart structure.
