New functionality for genreflex, adding the ability to select templated classes

with typedef'd template parameters. This functionality works for selection by
name and pattern. If a pattern is used the typedef name has to fully appear in
the pattern name. This new functionality is costly, so there is also new option
to genreflex "--no_templatetypedefs" to turn it off.
