0.4.0.0 now live

What's Changed

1. Improved error handling! The program will be able to handle most errors. If you see a error message please do report it into our issues so we can investigate further. The program will now run from start to finish without having to run 'python main.py' every time.
2. Code refactor: @AustinCGomez went through the entire code base and refactored everything to be much more readable and easier to maintain.
3. @malikrohail fixed #57 and we thank you for your efforts
4. Updated our README.md by @AustinCGomez

Short-Term Goals
](https://github.com/AustinCGomez/Python-File-Mover/issues)

1. Version 0.4.5.0 will release when all of the issues in the issue tab are resolved and that should mark the final development version of our project. We have some critical areas of improvements for the project revolving around logging and compatibility in Linux and OSX(Possibly). If you wish to see Version 0.4.5.0 happen faster then please take a look at our issues tab and pick up a issue. 🥇
2. Version 0.5.0.0 will focus on refactoring and bug fixing and documentation.

Long-Term Goals(After Version 0.5.0.0):
Python File Mover Retirement - We might evolve the program into a GUI application that will be a sister project of our command line interface based Python File Mover here. This GUI project will be in it's own repository and will only start after Version 0.5.0.0 is released which might be when we sunset the command line project. This is only a tentative plan and not set in stone.
