Implemented: New TWiki::Func::getRegularExpression Function to get Predefined Regular Expressions

getRegularExpression( $regexName ) ==> $pattern

Notes: TWiki internally precompiles several regular expressions to represent various string entities in an I18N-compatible manner. Plugins are encouraged to use these in matching where appropriate. The following are guaranteed to be present; others may exist, but their use is unsupported and they may be removed in future TWiki versions. Those which are marked "CC" are for use within character classes and may not produce the desired results outside of them.

Example:

   my $upper = TWiki::Func::getRegularExpression("upperAlpha");
   my $alpha = TWiki::Func::getRegularExpression("mixedAlpha");
   my $capitalized = qr/[$upper][$alpha]+/;
