Andy McFadden d42b9c6dc0 Add CheckedLoadString 
The static analyzer was annoyed that the return value from calls to
CString::LoadString() was being ignored.  This adds a wrapper
function that checks the value and logs a failure message if the
string can't be found.

* 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.
