* Banner announcement cuts off mailchimp on mobile
* Hide site version on mobile. Added version to footer as well in case someone _really_ needs to check it.
* Shrink pre-footer font size on mobile.
* Fix column breakpoint for force offline send (Was stacking, now remains side-by-side.)
* Reduce header dropdown sizes at mobile. Force gas dropdown to the left side so its not offscreen.
* Columnify contracts for better mobile behavior and less code.
* Remove leftover string interpolation
* Better mobile header / nav sizing.
