Attachment management, uploading and downloading.

### Package Specification

This package manages the JSPWiki attachment subsystem. It consists of three basic components:

- AttachmentServlet - the servlet which allows both uploading and downloading servlets.
- AttachmentManager - The JSPWiki Manager component which manages the storage of attachments.
- Attachment - A special kind of {@link org.apache.wiki.WikiPage} which stores a handle to the attachment data.

Attachments can either be static (i.e. real data, stored somewhere on a filesystem), or dynamic, which means that they're generated on the fly by a {@link org.apache.wiki.attachment.DynamicAttachmentProvider}.
