Improvement: edited settings.py and urls.py of widget_django_unchained folder to allow image posting.

1) Improvement and Clean: Models in forum app Post and Reply are easier to read. reply_chain fields in both Post and Reply are also removed as improvements in other parts of the Forum app made them unnecessary.
2) New Feature: Post model in forum app now has an ImageField to allow users to upload pictures.
3) Style: base.html added to templates folder of forum app to provide an overall design for the app. All HTML files extend from this file.
4) New Feature: post_details.html added to templates folder of forum app. Allowed to show individual post, associated picture, and reply section.
5) New Feature: index.html added to list down all posts in the database from newest to oldest.
6) Improvement: post_listing.html and replychain_listing.html are both removed. post_listing.html was removed and replaced by index.html. function better. replychain_listing.html removed because its recursive design was simply bad.
7) New Feature: post_form.html added to provide users the capability to submit new posts and replies. This feature is still under work and user access to it is disabled.

Meta: git repository config file modified with 'longpaths = true' value to prevent repository not updating properly when a filename (usually in the migrations subfolders) is too long.

New Feature: added forms.py for future development
