Update README.md

[Grossley]

Description

README.md has been changed in the following ways:

• Removed references to "Undertale: Bits and Pieces" from the readme.
• Changed the Flowey textbox to use Markdown instead of HTML formatting.

Caveats

None.

Notes

In my opinion, these changes are highly necessary, and implementing them is for the best for the community.
