cleanout: img/ with co-op js/3rd-party/ and css/3rd-party/ and css/themes/

hi there,

i finished directory structure cleanout on beautiful charisma template. please look to this pull-request. because i found some bug in yours code

ex:
1) some /css/bootstrap-*.css construction is constructed twice with the same attributes (it's useless)
2) img/thumb.png - is never used there (isn't it? in this pull request i delete that)
3) img/<many-files> is organized into /img/3rd-party/ and /img/charisma/ dirs to quick understanding of all organization inside templates (js x css x img)

bye and thx.
j3.
