Removing booking form submit button hooked function
Should never have been committed, doesn't work when EM Pro active, as that
takes over the booking form.
Login form in lightbox with custom m&m layout
Style booking form submit button via jquery
EM recommends we don't mess with the file that churns out the form, and
there is nothing to hook into or override for the button, so have to do
this via jquery instead.
Move login link to be above the booking form
Need to do this via jquery as once again EM gives us no control over how
the booking form and login is churned out.
