Support attachments for php5.6+, #364

Tested locally with php 5.5 and php 7.0.0

@bsvensson @esoekianto - I tested this fix. The file gets there, but something strange is happening. The uploaded file on my machine swaps out the file name for the file name + path on my personal computer. So the file attachment name will become something like this :

/private/var/tmp/Celebrate1.png

Also the ArcGIS machine receiving the attachment does not assign the proper mime type. So when I go to click on the attachment it automatically does a download vs a preview in the browser. My test results below.

{"attachmentInfos":[{"id":2947,"parentObjectId":111,"name":"/private/var/tmp/Celebrate1.png","contentType":"application/octet-stream","size":317839}]}

@bsvensson I should have said the above test results were for 5.5.7. So maybe I should disregard and test with another PHP version?

@phpmaps - if you're testing with pre-5.6 then the behavior should be the same with or without this fix.
