The 'pattern:' argument of Validators::is() crashed on a valid regular
expression containing a pipe, e.g. Validators::is('a', 'pattern:(a|b)').
Two parsing bugs combined: the expression was split into validators on every
'|', tearing the regexp apart, and the pipe was also used as the PCRE
delimiter. A 'pattern:' argument now consumes the rest of the expression and
the delimiter is changed to '~', with the pattern anchored as a whole so bare
alternations work too. Pipe-as-OR semantics for combined validators are kept.
Fixesnette/utils#206
