Moving documentation to ronn.

This way I can have one doc which gives rise to markdown/html and man.1

	modified:   doc/jedi.1
	renamed:    doc/manual.md -> doc/jedi.1.ronn
script to run ronn & a custom css file

	modified:   doc/jedi.1
	new file:   doc/make_doc.sh
	new file:   doc/ronn.css
Some documentation cleanup

	modified:   README.md
	modified:   doc/jedi.1
	modified:   doc/jedi.1.ronn
	modified:   doc/ronn.css
	modified:   install.sh
