File support? Discussion.

[radarsat1]

With more interest in adding file recording and playback to liblo tools (#74), it brings up interesting issues. The 1.1 spec proposes a MIME type and says that OSC should be recorded as a stream after such a header.

However, I point out in #74 that correct playback is impossible without also adding timing information. Additionally one cannot overlook the convenience of a text-equivalent format. Some more thought is required to decide how files should be handled, for liblo, but also generally for OSC.
