Combine scripts included in layout files

Eventually target is to have only one javascript file served, and that's
what Rails asset pipeline asset precompiling will by default do.
Removed Google analytics

Since Google analytics was used on meego.com only, and since it is going
down and has not been used/updated the whole thing was useless.
Removed unused images

jQuery UI images were for some reason included under images/ui_images,
and again in stylesheets/images (now vendor/assets/images). There was
no reference to ui_images anywhere so most likely they are not used.
