Resolves #42 "Update Styling based on feedback"

Closes #42 (closed)

Notes

Updates styling based on all the feedback given in the email attached to the issue, as well as the video, to the best of my knowledge.

Changes have been implemented to support both mobile and desktop versions.

All changes have been implemented as listed in the TODOs in the comments of the associated issue.

Added more YE Scotland logo files as well as updated references to YES to YE Scotland as major sticking points for the customer. Additionally updated colours to be more subtle and only using orange as a highlight, as well as making sure stylings are inline with their site.

Includes a couple minor bug fixes that are noted in commit messages and issue comments as not worth a full issue to themselves.

Relies on associated PR in core-fe which should be merged before this is merged.
