Stefan Brüns d47b857b09 Change data and shortHelpString to adhere to naming convention
Rename data to clientData in the inlined overloads. This change is
transparent for any users.

Rename shortHelpString to shortHelp (dito for longHelp). Although this
change is in general visible for any users, Phoenix already mangles the
the parameter names to strip the 'String' suffix.
