Mk/**java.mk: Convert bsd.java.mk to USES

The following features have been added or changed:
- Instead of USE_JAVA use USES=java. This defaults to
  USES=java:build,run if NO_BUILD is undefined. Else it defaults to
  USES=java:run
- Instead of USE_ANT=yes use USES=java:ant which also implies
  USES=java:build
- Instead of JAVA_BUILD=yes use USES=java:build. Does not imply run or
  extract
- Instead of JAVA_EXTRACT=yes use USES=java:extract does not imply
  build or run
- Instead of JAVA_RUN=yes use USES=java:run does not imply extract or
  build
- Instead of USE_JAVA=<version> use USES=java and JAVA_VERSION=<version>

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.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

This commit implements such a proposal and moves one of the WWW: entries
of each pkg-descr file into the respective port's Makefile. A heuristic
attempts to identify the most relevant URL in case there is more than
one WWW: entry in some pkg-descr file. URLs that are not moved into the
Makefile are prefixed with "See also:" instead of "WWW:" in the pkg-descr
files in order to preserve them.

There are 1256 ports that had no WWW: entries in pkg-descr files. These
ports will not be touched in this commit.

The portlint port has been adjusted to expect a WWW entry in each port
Makefile, and to flag any remaining "WWW:" lines in pkg-descr files as
deprecated.

Clean up after java/openjdk6 and java/openjdk6-jre removal

java/openjdk6 support was removed from Mk/bsd.java.mk (r512662) and
java/openjdk6 and java/openjdk6-jre were removed from the ports tree
(r512663).  Now this patch completely removes remaining stuff from the
ports tree.

Cleanup plist

- add stage support

Add NO_STAGE all over the place in preparation for the staging support (cat: cad)

Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits. With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be use

Logisim is used by students at colleges and universities around the world in
many types of classes, ranging from a brief unit on logic in general-education
computer science surveys, to computer organization courses, to full-semester
courses on computer architecture.
