ZendPhpInterpreter: throws exception on PHP startup errors [WIP]

[Closes #229]

👍 Tested on Windows and Debian. Maybe replace \r\n by ' ' and trim.

One "problem" is, that with php-cgi.exe on Windows, the error message I get with php.ini extension="foo.bar.dll" is:

$ Tester/tester -c php.ini tests/
 _____ ___  ___ _____ ___  ___
|_   _/ __)( __/_   _/ __)| _ )
  |_| \___ /___) |_| \___ |_|_\  v1.4.0


Error: PHP startup errors: PHP Warning:  PHP Startup:  in Unknown on line 0
.

With php.exe it works fine with appropriate message, on Debian CGI and CLI works fine.

$ Tester/tester -p php -c php.ini tests/
 _____ ___  ___ _____ ___  ___
|_   _/ __)( __/_   _/ __)| _ )
  |_| \___ /___) |_| \___ |_|_\  v1.4.0


Error: PHP startup errors: PHP Warning:  PHP Startup: Unable to load dynamic library 'ext\foo.bar.dll' - Uvedenř modul nebyl nalezen.
 in Unknown on line 0
.

IMHO nothing we can do with it since php-cgi.exe -c php.ini produces the same.
