Various bug fixes and changes

parse/1 now accepts dates with Days in them:
* Sat, 1st Jan 2011
* Friday 2nd Mar 1314

No attempt is made to verify the day of the week it is silently discarded
A comma is also treated as a delimiter/whitespace and silently discarded

parse/1 accepts dates decorated by timezone information:
* Sat, 1st Jan 2011 GTM
* Sat, 1st Jan 2011 DST
* Sat, 1st Jan 2011 UTC

Again no attempt is made to adjust times the TZ info is silently discarded

Some minor fixes, and a dialyzer warning removed as well

+Changes by Gordon Guthrie added under the

+
+This module formats erlang dates in the form
+{{Year, Month, Day}, {Hour, Minute, Second}}
+to printable strings, using (almost) equivalent
+formatting rules as http://uk.php.net/date
+
+erlang has no concept of timezone so the following
+formats are not implemented: B e I O P T Z
+formats c and r will also differ slightly
+
+See unit tests in the source code for examples
