Derive the custom hotkey renderers from wxDataViewCustomRenderer

Browse source 
Deriving from the more specialized renderes reduces the amount of code
required, but it depends on implementation details of the specific
implementations, resulting in the custom renderers not working with
wxGTK. In addition, this makes it possible to bypass the default
handling for 'Enter' which made it impossible to set it as a hotkey.

Originally committed to SVN as r6300.
