Changes for version 4.05 - 2014-09-08

RELEASE NOTES
- this release includes *significant* refactoring of temporary file handling in CGI.pm. See "Changes in temporary file handling" in perldoc
- this release adds a warning for when the param method is called in list context, see the Warning in the perldoc for the section "Fetching the value or values of a single named parameter" for why this has been added and how to disable this warning
DOCUMENTATION
- change AUTHOR INFORMATION to LICENSE to please Kwalitee
TESTING
- t/arbitrary_handles.t to check need for patch in RT #54055, it turns out there is no need - the first argument to CGI->new can be an arbitrary handle
- add test case for incorrect unescaping of redirect headers (RT #61120)
- add tests for the handle method (RT #85074, thanks to TONYC@cpan.org)
SPEC / BUG FIXES
- don't set binmode on STDOUT/STDERR/STDIN if a none standard layer is already set on them on none UNIX platforms (RT #57524)
- make XForms:Model data accesible through POSTDATA/PUTDATA param (RT #75628)
- prevent corruption of POSTDATA/PUTDATA when -utf8 flag is used and use tempfiles to handle this data (RT #79102, thanks anonymous)
- unescape request URI *after* having removed the query string to prevent removal of ? chars that are part of the original URI (and were encoded) (RT #83265)
- fix q( to qq( in CGI::Carp so $@ is correct interpolated (RT #83360)
- don't call ->query_string in url unless -query is passed (RT #87790) (optimisation and fits the current documented behaviour)
