v1.2.0

This was a massive code clean-up (and basically re-write at this point 😅) to use better code style practices and fix some bugs.

• The modal should show up in the middle of the view no matter scroll position.
• Adds a small sentence under the input to explain what a "social address" or "instance" is and uses the term "social address" as a more user-friendly term for main text.
• Now checks if the url entered has an https:// in front of it already, and if not adds it on blur.

v1.1.0

Adds greater customization of button and ability to replace the button all together.
