* Released 0.50

* Released 0.50

* Patch from Steve Grubb:
- bus/activation.c (bus_activation_service_reload_test): clean up
some indentation
- dbus/dbus-keyring.c (_dbus_keyring_reload): fix conditional
- dbus/dbus-message-factory.c (generate_special): fix a couple of
buffer overflows in the test suite.  This is non critical because
it can not be exploited and this code is only run when doing a
make check.

* Patch from Yaakov Selkowitz: Build fixes for Cygwin
- configure.in: Don't check and link against kdecore, only qt headers
- dbus/Makefile.am: Add -no-undefined to libdbus_1_la_LDFLAGS
- gcj/org/freedesktop/dbus/Makefile.am:
add libdbus_gcj_1_la_LDFLAGS = -no-undefined
- glib/Makefile.am: Add -no-undefined to libdbus_glib_1_la_LDFLAGS
and $(DBUS_GLIB_LIBS) to dbus_binding_tool_LDADD
- qt/Makefile.am: Add -no-undefined to libdbus_qt_1_la_LDFLAGS
- tools/Makefile.am: Add platform extentions to binaries
(i.e. .exe on windows)

* configure.in:
- Make it so if no suitable version of python is found we only
disable building python instead of exiting the configure script
- Require version 2.4 of glib for glib bindings
- Up version to 0.50

* python/__init__.py: Sync version with libdbus to (0,50,0)
