Add support for case conversion characters in regex substitutions.

Browse source 
Allow using Perl-like \l, \L, \u, \U and \E escape sequences in the
substitution string used with %rename("%(regex:/pattern/subst/)s").
This is useful for e.g. title casing all string after removing some prefix.

Closes #82
