feat: add optional hint/admonition icons (#383)

BREAKING CHANGE: The types of the `hint` short code have been renamed to `[note|tip|important|caution|warning]` the old types `[info|ok|warning|danger]` are still working, but should be considered as deprecated.

BREAKING CHANGE: The `hint` short code is using named arguments now. You have to change, e.g. `{{< hint warning >}}` to `{{< hint type=warning >}}`.
