Fixed INTERFACE script

The interface script was pointing at itself, causing an infinite loop. Also, it didn't have Set Error Capture enabled, so it was throwing the undesirable native error before throwing any desired dialogs.

Namespaced Custom Functions (with passthrough if available)

I updated all three Custom Functions to be namespaced to the Addon. This is because if you uninstall the addon, it takes the Custom Functions with it, and I don't want there to be any confusion about that.

I put plenty of comments in each one about how to create an extra-modular version of the CF, which will not "go away" when the addon is removed. Additionally, these are designed to pass through to any existing Custom Function matching the non-namespaced function signature.
