- mir_core.dll moved to the core :)

- plugins now obtain the fake langpack id if langpack is absent

+/*

+  Independent implementation of MD5 (RFC 1321).

+

+  This code implements the MD5 Algorithm defined in RFC 1321, whose

+  text is available at

+  http://www.ietf.org/rfc/rfc1321.txt

+  The code is derived from the text of the RFC, including the test suite

+  (section A.5) but excluding the rest of Appendix A.  It does not include

+  any code or documentation that is identified in the RFC as being

+  copyrighted.

+

+  The original and principal author of md5.c is L. Peter Deutsch

+  <ghost@aladdin.com>.  Other authors are noted in the change history

+  that follows (in reverse chronological order):

+

+  2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order

+  either statically or dynamically; added missing #include <string.h>

+  in library.

+  2002-03-11 lpd Corrected argument list for main(), and added int return

+  type, in test program and T value program.

+  2002-02-21 lpd Added missing #include <stdio.h> in test program.

+  2000-07-03 lpd Patched to eliminate warnings about "constant is

+  unsigned in ANSI C, signed in traditional"; made test program

+  self-checking.

+  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.

+  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).

+  1999-05-03 lpd Original version.
