* generator/ObjectGen.cs : suppress generation of get/set methods when properties exist. Mangle method names on signal name clashes. Gen the signals. * generator/SymbolTable.cs : Add GetName. Add some more calls to Trim. * generator/gtkapi.xml : adding binary file as an experiment. If the diff's show this file, I'll be removing it with apologies and going back to the separate package idea. * parser/gapi2xml.pl : some signal related fixes. * sample/HelloWorld.cs : uncomment the event hook. svn path=/trunk/gtk-sharp/; revision=2419
