Subject: [PATCH] Remove tabler.io JS (#254)

Only dropdowns and dismiss buttons were used, which are now
replicated with pure CSS or minimal JavaScript. This eliminates
the need for a heavy library. An added benefit is that dropdowns
can function without JavaScript, however, a drawback is the loss
of automatic dropdown placement.
