confirmation dialog on upload/download/remove files

[ubidefeo]

confirmation is delegated to a single function returning true/false based on message.
this solution is a temporary move towards having UI based confirmation panels

I would totally skip the confirmationDialog function. In case we really need it, it would be better with the other helper function at the end of the file.

This helper is being defined in the middle of the event handlers.
While it will work correctly, I would like this to be defined together with the other helper functions, at the end of the file.

Also why did you create a helper function for a native function that has exactly the same function signature as the abstraction?

This looks analogous to having a function called my_alert where inside you just call alert with the exact same parameters of my_alert:

function my_alert(msg) {
  alert(msg)
}

For the final confirmation box we'll do something very different from this so there is no reason to "prepare" for it like this.

I thought we wanted to hook into it at some point, that's why I brought it outside.
I'll make the changes later this evening, thanks you
