Support pushing of media files using multipart forms

Background

• Hosting companies impose size limits on the data that can be included in a POST method
• Some are set as low as 1MB
• Media files over 700K are likely to cause the total body of the POST to exceed the limits
• Generally, these limits are higher for multipart forms, where the files are sent in separate blocks of data

Requirement

• Use the multipart form method of passing media file attachments to the server

Solution

• Implement capability to send and receive media files using a multipart form
• Client uses [class OIK_clone_post_file]
• Server detects the media file by accessing $_FILES
