Remove standalone Jetty 6.x support scripts

In the 2.1 series we're strongly encouring everyone to switch
to using our embedded Jetty container (under our daemon command)
rather than installing and running their own external Jetty process.
It vastly simplifies the installation and maintenance of upgrades.

Also, Jetty 6.x is already (or very close to) being end-of-lifed.
The entire Jetty project moved to the Eclipes Foundation and
rewrote their package namespace during the 7.x release cycle.
A stable 7.x has already been released, and we're embedding it in
our daemon command.  So users who absolutely want to run their own
external Jetty container should just run Jetty 7 and use our jetty7
support scripts instead.
