Version with promisses

[gabrielrsep]

Summary

I think it would be interesting if there was a version of the database.run(), get() and all() methods that uses Promise instead of callback.
I can send a pull request with these changes, what do you think?

Proposed implementation

the database.run(), get(), and all() methods should be implemented using Promisses
