Bug description:DateTime::CreateFromFormat return false

Description:

datetime.createfromformat-returnvalues
---
I think that returning false is a bad behaviour that lead to surely
unwanted 
fatal exception when passing to it not well formatted dates.

This static method seems to be thought to get a datetime object on which
method 
format can be called inline:
DateTime::CreateFromFormat()->format()

But on not well formatted date strings the 'format' method raise an
exception 
E_ERROR because it is called on a boolean.

In my opinion CreateFromFormat should raise a throwable exception ( Best 
Solution ) or return an 
empty DateTime Object ( Unix Time 1970-01-01 ) and raise a warning, NOT a 
boolean value.


Test script:
---------------
php > var_dump( DateTime::CreateFromFormat('Y-m-d', '2013-05-') );
php > try { DateTime::CreateFromFormat('Y-m-d', '2013-05-'); } catch (
Exception $e ) { var_dump( 'ok' ); }
php > try { var_dump( DateTime::CreateFromFormat('Y-m-d',
'2013-05-')->format('dmY') ); } catch ( Exception $e ) { echo 'ok'; }

Expected result:
----------------
PHP Warning:  Uncaught exception 'Exception' in php shell code:1
string(2) "ok"
string(2) "ok"

//---------------
//alternatively the example should return an empty Datetime Object and 
raise a warning

}
