Capability to detect whether a database already exists without creating it

[pbenschop]

Hi Jens, I am with GreatVines in Portland, USA. We used IDBWrapper to create a mock implementation of the Salesforce SmartStore (a database component in the Salesforce Mobile SDK). Since SmartStore allows you to check for the physical presence of a "soup" (represented as a store in IndexedDB) without creating it, we added the capability to the openDB method to abort the transaction if the intent is to only check whether a database exists (without actually creating it). See the added cancelIfNew and CancelMsg options. Maybe this feature could be added to IDBWrapper.

Hi @pbenschop,

thanks for all your PRs! Really awesome to see that you're contributing back the changes you made to IDBWrapper. Please give me some time to look through these, that's a lot of code to check out.

Thanks again!

Hi Jens, thank you for putting this IDBWrapper together in the first place; great piece of work that provide me with good insight how IndexedDB works. In case you decide to accept these changes (which we hope), feel free of course, to change things around if you think there are better ways to achieve the same thing.

Hi guys, Do you plan to merge that? Or, it has been already implemented somehow?
