GCC 7.x does some extended checks on fallthough for switch/case
statement. The warning looks like this:

warning: this statement may fall through [-Wimplicit-fallthrough=]

It can be told about implicit fallthough, however it does not
recognize comments within blocks, so move the comments outside.

Several string pointer arrays pointed to const strings
but were not const themselves.

A few various structures and arrays were also marked const.

Before:
SpaceStyle EnterMove  DelDeleteEscDone  |
~~~~~      ~~~~~      ~~~      ~~~      |
UpUp     DnDown  LtLeft  RtRight EnterConfirmDelDeleteEscDone  |
~~       ~~      ~~      ~~      ~~~~~       ~~~      ~~~      |

After:
SpaceStyle EnterMove                                           DelDeleteF10Done
~~~~~      ~~~~~      ~~                                       ~~~      ~~~
SpaceStyle EnterLock  UpUp    DnDown  <-Left  ->Right          DelDeleteF10Done
~~~~~      ~~~~~      ~~      ~~      ~~      ~~      ~~       ~~~      ~~~

* 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.
