First commit of tabbed changes. Displaying files doesn't work yet, but the basic idea is pretty close.
Tabs for new projects working now. Have to do opened files
Datacontrollers working for multiple tabs. Next step is to get hotkeys working for different dataviewers.
Datacontroller hotkeys work
Opening files works. Saving does not yet work. Progress bar is broken (and disabled).
Saving works now.
Change tab name when file saved
Added close button to tabs. Close button needs to be hooked up to SafeQuit for files, and when closing Datavyu all of the tabs need to be closed in sequence using SafeQuit.
Tabs seem fully functional.
Split pane implemented. File tree implemented. Shows only opf files and directories with the root set to the file's current directory.
Only allow opening opf files from file drawer
Add icons to datavyu and ruby script files so you can tell them apart.
Removed some debug statements
