[MapProxy] ProjInitError

[Jason Lee]

Thanks Oliver, installing pyproj and setting a new Windows environment
variable MAPPROXY_USE_PYPROJ to True worked for me. Now I can start mapproxy
server in a normal command prompt (running within FWTools exhibited strange
behaviour, i.e. WMS requests were taking an infinite amount of time).
