Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Update to 0.15, sort plist, sort depends, use configure instead of modbuild,
remove the PORTDOCS that all other modules don't install, and add metacpan
as the first WWW which has more relevant information about the module.
