LPS-36335 Update Zoe Tech theme to use bootstrap CSS

Hey Rob, 

There's a few things that I wasn't able to figure out with this theme:

1.) The carousel menu still doesn't work. The tabs in the tab menu don't correspond to the pictures.

2.) The footer doesn't display. This problem occurred in the Zoe-Healthcare and Zoe-Political themes as well.

3.) When a new site is created based on the Zoe-Tech theme, the images don't display (However, they do display when viewing the template).

I've really appreciated your help and patience along the way.
