Renames Dewey to E53 Study Space on homepage hours and navigation

[djanelle-mit]

Developer

To prepare for the Dewey closure, we'll be renaming the library to E53 Study Space. We want to push this option down on the hours list on the homepage and in the navigation since it's less important to feature now.

This work moves the static references to this library and puts it below Lewis in both locations.

Note: the current "Unstaffed Location" checkbox will remove the phone number and the hours and the hours page will be updated via the hours sheet.

Looks pretty simple...probably one of the few times I wish that we'd made this widget more parametric somehow.
