Some Updates

Added a documentation folder for easy discussion between all authors, as well as list all bugs fixes, new features, and installation instructions. Read the file for the main developer. 

Also implemented OOP for MySQLi since I see us switching into OOP soon. Procedural code is not a proper solution so we shouldn't even code like this. We should use classes and functions to make things neater but this would require a full structural change.

I made some things more neater! I plan on making a todo list like you soon!
