Multiple fixes (menu, scroll, affix, responsive)

Main changes that need to be noted are template.html is intended to be
used when building out the different sections, but we need to decide on
the final structure before doing so. I am using
economic-development/build-page.html as the "testing ground" then making
the good changes to template.html

fixed anchor positioning
fixed sidenav scrolling (partial, needs work)
fixed in-page anchor padding issue
fixed border hover issue on main nav
added collapse to main nav on resize (size on collapse needs fix)
added expand to side nav on resize (mid-width spacing beween content
needs fix)

CSS Styling still needed but can be done after structure is finalized.
