Added the new pp hooks to Wave.

 - Changed the return value of the 'evaluated_conditional_expression()' pp hook
   to 'bool' allowing to force Wave to re-evaluate the current conditional
   expression. This was suggested by Felipe Magno de Almeida.
+- Added a wave::context object as first parameter to all pp hook functions. 
+  This is an interface compatibility breaking change. The new pp-hooks can be 
+  disabled by defining the BOOST_WAVE_USE_DEPRECIATED_PREPROCESSING_HOOKS 
+  compile time constant to something not equal to zero. By default this 
+  constant will be defined to zero for Boost V1.35.0 and newer, switching to
+  the new interface by default.

 <P dir="ltr">It is possible to use the <tt>Wave</tt> library while using your own token and/or lexer types. This may be achieved by providing your lexer type as the second template parameter while instantiating the <tt>boost::wave::context&lt;&gt;</tt> object. The token type used by the library is derived from the <tt>token_type</tt> typedef to be provided by the lexer type. If you want to provide your own token type only, you may use the <tt>boost::wave::lex_iterator&lt;&gt;</tt> type contained with the library. This type needs to be parametrized with the token type to use. </P>
