Pastebin

Summary:
This is Paste. It needs some work, but epriestley recommended that I just commit something that works, and expand on that later.

Specifically, it lacks the ability to view a raw paste right now, and to turn off line numbers, making it hard to copy/paste from for now. It works for showing other people code, however.

Test Plan:
Pasted stuff, and was able to view it, and see it in the list on /paste/. Put a file extension in the title, and saw that syntax highlighting worked as expected.
