Personal use case: `Android 6.0` w/ `DAVdroid 1.3.4.1-ose`, setting images on contacts
ContactsBackend.php does not handle v4 `PHOTO` properties, which produces the following error in: `/var/log/iRony/errors:`
```
[06-Dec-2016 15:55:16 America/New_York] PHP Fatal error: Call to a member function getValue() on a non-object in /usr/share/iRony/lib/Kolab/CardDAV/ContactsBackend.php on line 991
```
I belive the error is due to this code not handling `PHOTO:data:image/jpeg;base64,` well:
```
989 case 'PHOTO':
990 $param = $prop->offsetGet('encoding') ?: $prop->parameters[0];
991 if (($pvalue = $param->getValue()) && (strtolower($pvalue) == 'b' || strtolower($pvalue) == 'base 64') || strtolower($param->name) == 'base64') {
992 $contact['photo'] = $value;
993 }
994 break;
```
`PHOTO` spec https://en.wikipedia.org/wiki/VCard:
```
2.1: PHOTO;JPEG:http://example.com/photo.jpg
2.1: PHOTO;JPEG;ENCODING=BASE64:[base64-data]
3.0: PHOTO;TYPE=JPEG;VALUE=URI:http://example.com/photo.jpg
3.0: PHOTO;TYPE=JPEG;ENCODING=b:[base64-data]
4.0: PHOTO;MEDIATYPE=image/jpeg:http://example.com/photo.jpg
