[Koha-patches] [PATCH] Bug 13815 - plack loose CGI qw(-utf8) flag creating incorrect utf-8 encoding everywhere

[Dobrica Pavlinusic]

This is major problem for plack installations with utf-8 encoding.

In this case, we are overriding CGI->new to setup utf-8 flag and
get correctly decoded $cgi->params, and reset syspref cache using
C4::Context->clear_syspref_cache

Test scenario:
1. under plack try to search with utf-8 charactes
2. try to find patron with utf-8 characters
