#35 Adding user-defined ID3v2.3 frame

[Naoaki Okazaki]

This patch enhances LAME frontend to write user-defined ID3v2.3 frames,
introducing a new option --tv:
--tv <ID=VALUE>
An argument for the --tv option consists of ID and VALUE separated by
a '=' character:
ID: four letters representing ID3v2.3 frame ID
VALUE: text value for the frame
If --tv options are specified multiple times, this patch write all of
them in the appearance order as the command-line arguments.

Some existing options for ID3 tag can be specified by --tv option
as follows.
--tt <value>, --tv TIT2=value
--ta <value>, --tv TPE1=value
--tl <value>, --tv TALB=value
--ty <value>, --tv TYER=value
--tn <value>, --tv TRCK=value
--tg <value>, --tv TCON=value
(although some are not exactly same)

My initial motivation was just to add TCMP frame (flag indicating a
compilation album; typically generated by iTunes), but generalized to
--tv option, and realized with the command-line "--tv TCMP=1".
