/**
* A generic upload action for creating new images and saving them
* with tags, not not associating with any object.
*
* A straight forward add to pool action. Written to allow integration with other plugins
* or uploading contexts which don't involve the admin gen and an sfImagePoolImage form.
* Handles multiple files, all with same tags. Good for WYSIWYG editor integration.
*
* Checks for a 'tag' field name and uses this to add tags. Can be
* a CSV list or a single string.
*
* Only works with POST data, doesn't aim to replace any data (PUT).
