Love this plugin, just need some additional features for it to be usable

First, would love to have basic data validation. Since it only supports CSV, we should be able to do this:

<input type="file" accept=".csv" />

So that at the HTML level there is only CSV types allowed. Right now the app just crashes if you try to upload, say, a .Numbers file.

Second, and more importantly, we really really need a callback function somehow that gets fired when the user selects the file. Otherwise we don't really have a way to handle file saving once it's been uploaded. I feel like this is so basic that I must be missing something here??
