Saveable option is not passed right to bootstrap-markdown

[reppners]

The saveable option is actually spelled savable in bootstrap-markdown. This leads to non-functional saveable option in this component.

Would you be able to make a PR to fix it?

Nevermind, I understood after looking at the code. I made fix, actually I accept both saveable and savable, so if they ever fix it then the package would still work.

Give it a try, report back if not working. Thanks
