upse2 snapshot build for foobar2000 available

kode54 has uploaded a foobar2000 component using a recent mercurial snapshot of the upse2 PSF playback engine. You can download it from his website.

A prerelease of upse2, upse-1.90 will be made within the next few days.  I would like to give thanks to TMM and kode54 for contributing code and ideas to this release, as well as the people who generally test UPSE snapshots for accuracy and playback compatibility.
