Features:

• Images are now compressd to aroun 1 MB when uploading to firebase, and their size restircted to 1350 (max height) and 1080 (max width).
• Implemented connectivity to monitor connection to the internet and have the UI properly tell the user when they're disconnected off of the internet. (Still need to be wary for android users though...)
• Creating a new event now redirects the user to the correct index of the account page

Fixed Bugs:

• Accidentally called readAsBytesSync() in a widget's on pressed function causing the UI and images to load much more slowly in the list view.
