* FIX format parameter
To be able to print files in raw format it's needed to set this parameter.
Previous code was not able to print raw files, but it didn't get error because 'format' used on line 107 is assumed as a format funtion, because format parameter was not on this scope.

* [FIX] Fixed the print_document method of report
The new API migration was made to @api.multi because of the "cr, uid,
ids" signature, but "ids" was the ids of the records to print here, not
the report's ids.
Also, the new API version of "get_pdf" get directly the ids of the
records to print in the standard module, not a recordset.
* [FIX] UI is now (un)blocked only when using qweb-pdf reports in standard addons
