(fix) register OnEnter rules (#236)

[b-fuze]

Register OnEnter rules for proper auto indenting. Fixes #236

[b-fuze]

All the lint errors seem to be related to the very long regex used in the OnEnter rules. Should I make eslint ignore those errors or attempt to fix it somehow?

hah, yeah, I'd make eslint disable the line completely

Thanks for the PR! Could you for each regex add a short comment roughly explaining what it does?

[b-fuze]

@dummdidumm I actually copied it mostly verbatim from https://github.com/microsoft/vscode/blob/master/extensions/html-language-features/client/src/htmlClient.ts#L209-L226

Should I write a short comment explaining how I understand it?

[dummdidumm]

That would be great!
