detaintPath() and detaintPathAllowAbsolute() removed '://' with a single
str_replace() while the '../' removal below them already looped. One
pass is not enough, because removing a match can join its neighbours
into a fresh match: '::////' collapses to '://'. So
'php::////filter/read=string.rot13/resource=/etc/passwd' came back out
of the filter as 'php://filter/read=string.rot13/resource=/etc/passwd',
reinstating exactly the wrapper the strip exists to remove.
Loop the '://' removal the same way the '../' removal is looped. These
functions guard $view, $request, $action, the modal name and skin file
paths.
