- bump PORTREVISION

As side effect, I completely disabled --update feature. It was done for number
of reasons:
- subversion relationship starts not only if --update feature is requested by
  user, but when pysvn or svn is available
- we do not installing repository metadata from the source tarball (exactly this
  breaks the --update option, but it is broken anyway, see below)
- aforementioned repository metadata is not compatible with svn 1.7, that is in
  ports now
- development repository moved to github from subversion hosting anyway

This is accomplished with replacing the call of getRevisionNumber() with static
const, that represents the svn last revision from tarball.

while here:
- trim Makefile header
- remove indefinite article from COMMENT
- convert to optionsng

main server. (These are represented by coloured boxes, so you could
also imagine them to be water mains, electricity cables, phone lines, etc.)

In this version, not only must every terminal be connected, but every piece of
cable must also be connected to the main server somehow.
