Updated libopenmpt to 0.2.8190.

libopenmpt 0.2-beta24 (2017-05-22)

    [Bug] localtime() was used to determine the version of Schism Tracker used \ 
to save IT and S3M files. This function is not guaranteed to be thread-safe by \ 
the standard and is now no longer used.
    [Bug] Compilation with GCC 4.1 was broken since 0.2-beta20.5.
    Improvements to seeking: Channel panning was not always updated from \ 
instruments / samples when seeking, and out-of-range global volume was not \ 
applied correctly in some formats.
    Work-around for reading MIDI macros and plugin settings in some malformed IT \ 
files written by old UNMO3 versions.
    Improve tracker detection in IT format.
