Fix typo
Don't show size for now
Move slide_stack to utility

So it's available for the TinyMCE plugin. It runs via Ajax and the admin
class is not loaded there.
Improve get_slide_image_src. Add get_image_size.

Also move slide_stack here from Lucid_Slider_Admin.
Increase specificity and *gasp* add an !important

I feel there will never be a need to have a list style on the slider and
if so, custom CSS can be used instead. I noticed the need for a
specificity increase due to Twenty Twelve's '.entry-content ul' rule
that sets margins and other stuff, overriding the single class name
selectors.
Save image size name and allow custom sizes.
