Use Capital Framework colors

[cfarm]

Removes brand-palette and cf-theme-overrides from the main.less file so that colors come from Capital Framework instead.

Additions

-

Removals

• delete cf-theme-overrides

Changes

• upgrades to latest Capital Framework components
• add font variables to main.less (these were in cf-theme-overrides, they are not default in Capital Framework yet, but that change is on the way)
• add icon font path to main.less (this was also in cf-theme-overrides)
• remove import of brand-palette.less. for now this is still in project until we can resolve how to manage it since designers update colors here.

Testing

1. git fetch && git checkout use-capital-framework-colors
2. ./setup.sh
3. npm start
4. Confirm brand colors appear correctly at http://localhost:4000/page-components/page-components.html and localhost:4000/brand-guidelines/color-principles.html

@anselmbradford please ignore the travis build. I just enabled travis for this repo last week to test out some scripts on another branch; we don't need anything to pass for this to be merge-able.
