Fix incorrect export in TS declaration

[jclusso]

Closes #15 and is a simplification of #16.

@vgoloviznin what do you think of this?

Getting all declarations in a single file is not correct from the TS POV as you actually miss what's being exported from other files than emailable.js.

However, from getting the typings just for the emailable file this is correct and will work.

I've also updated my PR with extra typings, the auto-type-generator missed them and I didn't spot this.

So is this sufficient to make TS users happy? That's really the goal here and I'd like to avoid cluttering the project with extra files.

I noticed those regressions to a few of the fields. This PR should already handle them I believe since I incorprated the changes from your PR and the original.

Thanks for your help!

This should be sufficient, yes, as it fixes the main issue of the emailable export. You're welcome!
