Libraries Moved From bin To lib

In Texis version 8 and later, shared libraries (.so* files under Unix, .dll files under Windows) shipped with Texis that it uses have been moved from the bin subdirectory to the lib subdirectory (of the Texis install dir). This reduces clutter in the more visibly used bin directory, and is more in line with typical package layouts. (Note that the libraries used when linking with the Texis API remain in the api directory.)

In addition, the token %LIBDIR% was added to refer to the library directory, for use in texis.ini (here), vhttpd.conf (here), <vxcp libpath> (here), and anytotx's formats.rule file.
