#156 Ubuntu integration issue related to MIME type association

[Hibou57]

Another issue, related to Ubuntu integration this one (may need to be forwarded to the Ubuntu package maintainer): the “qtpfsgui.desktop” file does not associate qtpfsgui to any MIME type, while it could be associated to either “image/hdr” or “image/x-hdr” or both (there seems to be an issue with “image/hdr” which does not seems to be an officially registered MIME‑Type) or more simply to “image/*”. The Ubuntu package would also benefit to contain a MIME‑Type definition file (as defined by the FreeDesktop standard).
