Andy McFadden d8223dbcfd Relocate method comments 
This moves method comments from the .cpp file to the .h file,
where users of the methods can find them.  This also makes it
possible for the IDE to show the comments when you mouse-hover over
the method name, though Visual Studio is a bit weak in this regard.

Also, added "override" keywords on overridden methods.  Reasonably
current versions of popular compilers seem to support this.

Also, don't have the return type on a separate line in the .cpp file.
The motivation for the practice -- quickly finding a method definition
with "^name" -- is less useful in C++ than C, and modern IDEs provide
more convenient ways to do the same thing.

Also, do some more conversion from unsigned types to uintXX_t.

This commit is primarily for the "app" directory.

* Disk editor implementation.
*
* Note to self: it should be possible to open an image in "nibble" mode,
* switch to one of the various "sector" modes, and maybe even try out a
* "block" mode for a while. Locking the editor into one particular mode
* makes for a cumbersome interface when dealing with certain kinds of disks.
* It should also be possible to configure the "custom" NibbleDescr and then
* re-analyze the disk, possibly transferring the customization over to
* the main file listing. (Perhaps the customization affects a global slot?
* Probably want more than one set of custom nibble values, with the config
* dialog accessible from main menu and from within disk editor.)
*
* A track copier would be neat too.
