cfg_radio table - some (perhaps) odd entries

[sheridat]

The 499 row id is a placeholder row that separates the built in moOde stations from user-added stations. There is a code block behind the new Radio Manager dialog that tests the row id and the station type to support a Show/Hide feature.

I decided to keep rows for stations whose playable URL was no longe valid or where in some cases the stations no longer existed. They have "DELETED" in the station column. It makes it a bit easier to reuse the rows in an in-place update.

Thanks Tim
