Add an information page

[gannonprudhomme]

We should add a page / dialog that discusses various things about the website, including:

• How often we scrape and such
• Maybe more "hidden" features of the website (like saving a schedule?)
• ~~Origin of the project? Why we started, what we're aiming for, the fact that it's student made and such~~
• Some vague things, like how by default if you have nothing selected in section customization level it's the same as having all sections selected
• We don't show course titles per section, so you'll have to use Howdy to browse classes like KINE-199 or CSCE 491(?) (Ryan has others)
• We combine (exam) meeting times that overlap with each other to reduce confusion/clutter
