[EHPweb] ImageMagick/Apache on ehpdevel

[Jeremy M Fee]

Hello,

This change may affect postscript conversions when the postscript file  
includes transparency.

This updated version of ImageMagick was causing problems while  
generating basemaps.  In this newer version, ps:alpha was made the  
default instead of ps:color, and so far there is no command line  
arguments that override (tried -colorspace and -alpha).  This  
workaround unfortunately affects all users, but will hopefully not  
introduce new problems.

I updated the ps:alpha delegate configuration to match the ps:color  
delegate, in /usr/lib/ImageMagick-6.5.6/config/delegates.xml , by  
changing -sDEVICE=pngalpha to -sDEVICE=pnmraw.
