Create a manage.py for the project

[xvjg]

Similar to how Django's manage.py works.

I propose the following features:

add.sh convert to -> python manage.py add

collect.sh convert to -> python manage.py collect

Run flask app -> python manage.py run

Run Tkinter app -> python manage.py tkrun

[Compro-Prasad]

add.sh convert to -> python manage.py update-meme-types

collect.py convert to -> python manage.py get-memes

Run flask app -> python manage.py serve

Run Tkinter app -> python manage.py tkinter

Also make manage.py executable and rename it to something unrelated to Django. Add the following header too:

#!/usr/bin/env python3

This will allow executing it like: ./manage.py <args>
