This eliminates nearly all of the user-facing references to Observium, including in the names of temporary files and in the metadata of PDFs. Many of these may not be used any more, but I've adjusted them anyway. These changes should also make it easier to change the branding later if it is needed. There are a few references of which I still don't understand the significance, so I've left them as-is for now. The Unix agent in particular is rather untidy.
