BugTrack2/369 Support PHP7 - Remove '& new Class' notation

BugTrack2/369 Support PHP7 - Remove '& new Class' notation

Backward incompatible change of PHP7:

New objects cannot be assigned by reference
 The result of the new statement can no longer be assigned to a variable

http://php.net/manual/en/migration70.incompatible.php#migration70.incompatible.other.new-by-ref

Deprecated code:

```
class C {}
$c =& new C;
```

Solution:

```
class C {}
$c = new C;
```

These code changes will cause PHP4 imconpatibility in some cases.
