https://issues.itk.org/jira/browse/ITK-3183

Change-Id: Idefce0cb502d47c479d22969bc182d8ce38db569
ENH: Upgrade doxygen config file

Since nightly doxygen documentation use doxygen 1.8.4, the config file needed
to be updated.

Change-Id: Iae664942887fd856de5f8d0853707e8d23608a4b
STYLE: TScalarType -> TScalar

According to ITK Style Guidelines, for type XX, TXX is used in the template
declaration, and "typedef TXX XXType;" is used within the class to refer to
the type.
