Version 1.1 Build 23

- We’ve added a CodeKit config file thanks to the release of CK2. This
should help with collaborators using CodeKit.
- The masthead logo should now be in the center of the website on
tablet sizes instead of on the left.
- A RWD issue got fixed. Multimedia archives should be significantly
less squashed together than before. As such, Issue #15 is closed by
this build.
- Dark theme menu links no-longer have a confusing :hover state on
mobile.
- A SASS file for logged in users has been added for logged-in specific
styles.
