Changing projection via cgi request using 5.0

[Steve Lime]

Oliver: This is a bug. I filed a ticket and have already fixed the problem in the main SVN
trunk. See http://trac.osgeo.org/mapserver/ticket/2335. There is no workaround but the
change is simple. In maplexer.l, around line 258 change:

<INITIAL,URL_STRING>projection                 { return(PROJECTION); } 

to:

<INITIAL,URL_VARIABLE,URL_STRING>projection    { return(PROJECTION); }

and rebuild.
