Use Text.rich rather than RichText

[amake]

Text.rich handles selection and text scaling for you automatically.

Fixes #70

Hey @amake, was just about to do a PR for this, here is a correction you need to make, RichText and Text.rich are more or less the same and both don't have selection, you should rather change the Text.rich to SelectableText.rich, Cheers👍.

Please read my comment on #70. SelectableText.rich is not the right thing to use here.

Should have read the entire issue and not just the title before I commented, it makes sense to make it optional, well thought.
Let's hope they merge it soon, package looks abandoned, how ironic 👀
