Version 1.0 release

This release is an improvement on the plugin that was shipped with kairos. The following improvements have been added:

1. Ability to limit the size of files before they are zipped up.
2. Disk space checker to prevent filling up the disk - the code deletes old upload files resulting in data loss but prevents the disk from filling up.
3. Connection timeouts have been added to the upload client. Previously connections could hang indefinitely.
