Updating to new version

I have a suggestion, how to make Mp3tag more user friendly

Now the [small] problem is, that with every update I make, by installing a newer version, I get the default actions and exports installed once more. So every time I need to remove them, because I don't use them [and they only take precious space and make things less visually clear]

Thus it would be nice if the installation would first check for an existing copy of Mp3tag and ask the user if the default actions / exports are to be installed at all. [And the question part is important, becasue maybe some day I may need those ready to use scripts]
