Refactored helpers.
- Replaced _helpers.scss logic with one breakpoint loop.
- Removed previous breakpoint helper mixins (responsive_*).
- Added "no-border" to definable list of $border-helpers
Refactored navigation.
- Rewrote to be mobile first (start off as hamburger)
- Replaced “hamburger-mode” mixin with “bar-mode” mixin
- Added "bar" selector to navs that specify point at which navigation becomes a dropdown/bar.
- Added $navigation-base setting for defining default-base for navigation selectors (defaults to $default-base)
Refactored html.
- Changed docs to use new mobile-first syntax.
- Removed reference to “breakpoints.scss”, since breakpoints are defined in settings already
