FileDetailsView (accidental renaming should now be rare).
- Fix keyboard support for edelib::ExpandableGroup in FIV. The remaining bugs
are in ExpandableGroup class and not in efiler.
- Rename FileView::setType() and getType() to type(), for consistency with
fltk
- Fix hiding of views in type()
- Remove some old commented code (shouldn't be needed ever again)
- Make the selecion box around icons rounded
- Show "directory not found" error when needed (previously, efiler would
silently jump to home)
- Fix DirTree not respecting default settings
- Attempt to fix callback for dirtree - impossible - documented in BUGS so
someone could fix it someday
- Selecting with Space key and increasing selection by holding down shift
