added missing close tag
tinsy spelling fixes
added options:
 - format: all options that the qrserver api supports
 - bgcolor: so you can specify the background colour as well as the foreground colour - make sure to maintain a reasonable contrast or readers won't like it.
enable picker for the background colour
ECC option
margin and qzone parameter editing - with sliders (jquery UI based)
Image for the menu icon

It would be nice if the TinyMCE api docs were better... like specified
what object properties do what/what tinymce does with them.
added toggle function
moved most qrcode.html js into js/qr.js
minified js/qr.js -> js/qr.min.js
move extra options into advanced/extra fieldset which only shows if clicked.
revamp of  ui to avoid having to scroll (unless advanced options are shown).
Merge pull request #2 from PacificMorrowind/master
