Expose File Select Dialog

[xentripetal]

It would be useful to expose the file selecting dialog for getting paths from the user as an alternative to giving the path as a a string input via Dialog.entry.

Suggested Features:

• Configuration for dialog title (e.g. title="Save File"/"Load File")
• Configuration for supported file types that will filter the available files to those matching. (e.g. filetypes={"png","jpg"}
• Callback for user selecting file (e.g. OnSelect=function)
• Selected file stored as path string in dialog data.

👍 thought about it but didn't have enough time to make it in beta4, maybe for the final v1.2.10
