HyperVIBES: Pure CSS submit button

New feature

Implement SubmitButton component in pure CSS.

Problem to be solved

Currently the SubmitButton component is implemented using a static PNG background, which makes in inflexible to dynamic content changes. Update it so it's implemented using purely CSS.
