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

A few various structures and arrays were also marked const.

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.

Keep panel structure up-to-date as process list changes when headers are updated during the screen manager. Hopefully closes #3444533.

Reduces resulting code size.

Add CPU affinity screen ('a' key).
BUGFIX: Correct display of TPGID field.
Add TGID field.
