textproc/docproj-jadetex

Updates to textproc/docproj* ports:

o textproc/docproj-jadetex:
   - Remove port; functionality is moved to
     textproc/docproj

 o textproc/docproj-nojadetex:
   - Remove extraneous MAINTAINER line
   - Trim headers

 o textproc/docproj:
   - Trim headers
   - Convert to new options framework
   - Default to WITH_JADETEX=yes
   - Make devel/subversion dependency optional while
     noting it is required for source checkout; this
     allows us to skip svn and dependencies for release
     builds
   - Bump PORTREVISION

 o Add UPDATING entry explaining who needs to update
   port origins

 o Add MOVED entry for textproc/docproj-jadetex

- Fix dependencies. - Use WITH_JADETEX instead of JADETEX. - Use USE_GHOSTSCRIPT.
