ID3v2: Properly handle solidus character (U+002F) in text frames

Browse source 
V2 and V3 allow for the separation of multiple values with the solidus (/) character, while in V4 the separator is null (0). This was not accounted for previously, and would break valid V4 strings ("Foo / Bar" would be split into "Foo " and " Bar").
