[Jsynthlib-devel] copied across pages

[Frankie F. <jsy...@te...>]

I've copied across the main pages from the old jsynthlib.org website -
the user guide, programmer info, supported synth list and the contribute
page. They need a bit of tidying up and some of the info looks a bit out
of date so I've only linked the synth list from the main page of the wiki.
