[xslt] plugin rpms uploaded

[joel reed <joelwreed comcast net>]

I've uploaded rpms for the libxslt plugins regular-expressions and
dates-and-times. I also updated dates-and-times to compile against
gcj-4.0.

The files can be obtained here:

regular-expressions implements regexp:test, regexp.match, 
and regexp:replace using PCRE.

dates-and-times implements format:date using libgcj.
