Also build dependencies at the same directory as evolution files
and build 'master' configuration by default (it used to build 'stable'
configuration instead).
* use e_util_win32_initialize() in main() to avoid code duplication
* e-spinner - correct image path build under win32
* export WIN32_SERVICELIBEXECDIR when building eds, which relies on it now
* update D-Bus patch and session-local.conf creation, thus D-Bus
can actually autostart services
It can contain only one folder, thus use the one from evolution's
build directory. The dependency's folder might be added by a relative
path from the glib's DLL file.
