handle reading strings better
Strings are LATIN1 in Flash <= 5 and only became UTF8 in Flash 6.
swfdec_bits_skip_string () has been removed because of this and
swfdec_bits_get_string_with_version() that automatically does the right
conversion.
swfdec_bits_get_string() should be considered deprecated. Someone should add
some tests to ensure all strings behave like this and switch the rest of the
functions.
