Align Terminology of Model Classes / Public API

[wba2hi]

Is your feature request related to a problem? Please describe.
Our terminology used inside the SDK is not consistent to the "real world". While the "VSS Specification" contains a list of all Vehicle Signals, we have a base class named "VssSpecification". All our generated classes extend this "VssSpecification".
While it's true, that each of these classes are part of the VssSpecification each element on it's own is not the "VssSpecification".

Same with the annotation. The only annotation which is used to reference the VssSpecification file is named "VssDefinition". While this is a valid name, a more appropriate name would be "VssSpecification".

PropertyListener also is chosen arbitrarily but it also probably needs the same name

The naming "VssSpecification is also redundant as VSS means "Vehicle Signal Specification". Therefore A VssSpecification is a "Vehicle Signal Specification Specification" :D

Describe the solution you'd like

• Rename VssDefinition -> Vs(s)Specification
• Rename VssSpecification -> VssSignal / VssElement / VssNode / ...
• Rename VssSpecificationListener -> VssSignalListener (?)
• Rename PropertyListener -> VssSignalListener (?)
• check other models for inconsistencies with "common names"
