Fix wxHash{Set,Map} compilation with g++ 4.7 in C++11 mode.

Fully qualify the hasher and comparator classes used with
WX_DECLARE_HASH_{SET,MAP} macros as they're used as base classes by the
standard library implementation in g++ 4.7 and using them without the scope
operator results in compilation errors because they're interpreted as being
(inaccessible) base classes and not the global ones.
