* Align 'Delete' and 'Done' to the right to match functions on other
  screens. (Accidental clicking is avoided as a side benefit.)
* You could change meter type while in moving mode. New bar now hints
  this.
* Two Enter key functions are put in the same place and so mouse clicks
  there act like functions toggle. (The wording change to 'Lock' is
  also to reflect this.)
* '<-' and '->' instead of 'Lt' and 'Rt' abbreviation as the latter is
  not widely seen and arrows shapes are obvious. :)
* 'Esc' key for 'Done' in this context may not be intuitive, comparing
  to 'F10'. While I wish there be a Cancel/Undo function for 'Esc', it
  wouldn't hurt if we write 'F10' for 'Done' on functions bar for now.

Per @hishamhm's suggestion. This is UI change only.
In code the class names and symbols still refer them as "modes".

Before:
[Up]Up [Dn]Down [Lt]Left [Rt]Right [Arrow]Confirm [Enter]Delete [Del]Done

After:
[Up]Up [Dn]Down [Lt]Left [Rt]Right [Enter]Confirm [Del]Delete [Esc]Done

This is a work-in-progress, code is currently broken.
(Some actions, and notably, the header, are missing.)

Changes in object model: separate class objects to store vtable. Also, nicer UTF-8 display of big numbers.

Reduces resulting code size.

- add AllCPUsMeter;
- because of that, the new .htoprc is incompatible with previous released versions.
