clients.sass file change and exclude the_design.psd

Prepended _ to the clients.sass file so that it isn't compiled into its
own script.
Excluded the_design.psd from being from the outputted site files.
Prepended _ to animations

Prepended _ to the animations and spinner to stop them from being
compiled to a separate file.
Moved the animations out of the nested folder since there was only 1
item per folder.
