Updated remind to version 3.0.21:

Updated remind to version 3.0.21:
- adds "cm2rem" to convert from CDE's "cm" calendar manager to remind format.
  [needs tcl-8.0, but the pkg does not require it for just this small script.]
- adds "remind.vim" file for Vim syntax highlighting of Remind files.
  [installed in ${PREFIX}/share/examples/remind.]
- new "dusk" and "dawn" built-in functions.

The distribution site has changed, which is what primarily prompted for this
package upgrade.  The old distributions don't seem to be available anymore.
