- Ensure proper doctype https://github.com/bootstrap-email/bootstrap-email/commit/8b72de6c8ea860662b23a948852175639c821aee because of https://github.com/bootstrap-email/bootstrap-email/discussions/168

What's Changed
* Support partial url tokens by stuyam in https://github.com/bootstrap-email/bootstrap-email/pull/172

Before you could do something like this `<img src="{{ some_code_here }}">` but not like this `<img src="https://example.com/{{ some_code_here }}">`. This fixes that and allows text before and after handlebar style tokens in urls.

Thanks to psociety for opening this issue 160
