task/WG-167: Overhaul questionnaire style (#169)

* Initial commit to get the Questionnaire redesign rolling. Initial resize of the modal window to begin improving layout and styles.

* Added comment to evolving styles.

* Initial pass removing all font-sizes and color form the questionnaire modal. Next is to prune out the margins and spacing. Need clean, unstyled text in the UI to build new CSS back up on.

* Removed all font weighting, font type assignments and font size assignments from selectors in questionnaire modal.

* Commented out most of the styling in the questionnaire at this point.

* Have now commented out all styles that are not required for basic structure. Purging unused code next.

* Removed all unused selectors from the .styl document for questionnaire viewer. Ready to rebuild the style back up now.

* Completed the initial rebuild of the Questionnaire viewer styles to integrate with the Hazmapper design aesthetic. Still working on a few question types - ranged options specifically - but otherwise clean layout now.

* Added styling for the rangeAnswer elements. None of the questionnaire content indicates a selected state so I set a value anyway in case we update the view code to include that attribute.

* Changes the scope of image selectors in the questionnaire to only style images embedded within the questionnaire modal. Added support for both rangeSelect question and matrixTable question styling. Adjusted overall font sizes and layout for better legibility and use of white-space.

* Ran linting on the css.

* Cleaned up a mistake in css. Linting seems to regenerate unused style code locally. Investigating, but this commit is clean.
