[ingo] escaped strings in _year (_month, _day) Check functions (sieve.php)

[Serge Chernyavsky]

Hi All,

I use latest webmail groupware edition and dbmail-timsieved.
After saving vacation script I had regex strings looked like:
--
if header :regex "Received" "^.*(2009) (\\(.*\\) )?..:..:.. (\\(.*\\) 
)?(\\+|\\-)....( \\(.*\\))?$"
--
in my sieve database which obviously doesn't work.

It's returned by _yearCheck and similar functions which have 4 
backslashes in a row in return strings which causes this. Not sure if 
it's required for correct behavior with other sieve implementations but 
with dbmail it only works if I replace '\\\\' with '\\' in above functions.
