Small changes

[nghtctrl]

• Merged the .gitignore to the top-level directory. We now have only one .gitignore file to concern ourselves with.
• Removed unused/unrelated server.py (not Ray's) from comments-wrangling and reflectia to avoid confusion.
• Reformatting and stylistic changes to the server.py (Ray's) code.
• db_file variable is used to refer to "requests.db" now.
• Updated dependencies list.
