(#7) - Allow db names starting with underscore

[marten-de-vries]

Fixes #7.

Good catch. However, since copies of pouchdb-all-dbs are already floating around out there in the wild, I'd like to see some basic migration logic (e.g., whenever you pull something out, check if it starts with db_).

[marten-de-vries]

Agreed. I'll look into it.

[nolanlawson]

don't worry about it, I gotcha. it's a one-line code change :)

[marten-de-vries]

Thanks.
