Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Removed the implib_dir instance variable because it is unused. Removed get_ext_libname() because it is unused. Fixed get_libraries() to append an '_d' to the python debug import library. If MSVC is used, do not add 'pythonxx.lib' to the list of libraries, because this is handled better by a pragma in config.h. This should fix bug #115595, but it needs some more testing.
