Trying to recreate an existing database

[Wanderer]

I have already created a database from a specific version of mame.exe but for some reason i decided to recreate it. When i was prompted for the database filename, i selected the already existing one and pressed "Save". RC, instead of asking me if i wish to overwrite it (as i expected), it instead informed me that the file already exists and did not permit me to continue. I think to would be better to ask the user if he wishes to overwrite the file.

Yes, I know that.
I did that because it's not clear if someone want to replace the file, or update it. In the latest case, he expects to have all his folders back (and use the update method for that).

You have to delete it before proceed (you can do it directly from the file dialog).

Of course, I could improve this part later.
