In addition: - moved video type detection into a separate file: videoTypes.dt out of datatypes.dt. Also, removed all actions from Antonis' dt files, as these are handled by the new actions (listed below). Image, postscript, and PDF types definitions are still located in datatypes.dt.src - supports most image files, PDFs, postscript files, and video files via dtapp now. - Added new actions: - DisplayImage - DisplayVideo - DisplayPDF - DisplayPS All of these call the dtapp_* helpers to locate an appropriate program to handle the task. - Added a camera icon - standardized the icons used to display the various types - all images use the Dtimage icon now, as an example. - moved the new *.dt files to their proper place in programs/types, rather than programs/localized/C/types (my bad). Please add any further video types into videoTypes.dt, and everything else (for now) into datatypes.dt. In the future, we should probably separate these out into type-specific .dt files. Also, something should be done about playing audio files too (maybe DisplayVideo.dt can handle all those too?)
