This PR was done mostly cause of reports about invalid/not supported types/variables in phpstorm/scrutinizer-ci, and after I started fixing I noticed more problems in those phpdocs so I have cleanedup them a bit.

\* Unless you are parsing the response string manually, which you really shouldn't do anyway

**THIS IS A SECURITY FIX AND SHOULD BE MERGED SHORTLY**

This fix prevents attacks vectors where third-party browser plugins depends on ASCII magic bytes in order to execute a plugin. This is currently exploited with Flash using a carefully crafted JSONP response, allowing the execution of random SWF data from a domain with a vulnerable JSONP endpoint.

This security issue is mitigated by adding an empty comment right before the callback parameter. This does not affect the execution of the JSONP callback.

Remove Spaceless Blocks From Twig Templates

Leaving it in can only mangle values from data bound to the form.

The tests pass here, but it doesn't seem like any tests really cover the actual rendering.
