Feature: ability to fetch files from lib/assets

[williams-jack]

Problem Description

We should be able to access publicly available (e.g., tester.jar, checkstyle.rkt, etc.) files from Bottlenose. These

Solution

• Route for /resources added to config.
• FilesController updated to handle files coming out of lib/assets.
• Testing added for both upload and resource methods of FilesController

Additional Notes

Initially was thought allowing any file in lib/assets with introduce a directory traversal vulnerability, however Rails seems to auto-magically collapse ../ into just /.

Logic is sound; abstract out test and controller logic into helper (for each).
