Subject: [PATCH 1/8] Rename String to StringUtils

htop uses scanf functions to parse values from proc filesystem. This
breaks when initializing locale for LC_NUMERIC because of unexpected
commas. So initialize locale for LC_CTYPE only.

This has two effects:

* The locale may have impact on string formatting. So depending on the
  locale we may end up with different decimal point.
* We can use nl_langinfo() for UTF-8 detection.

... and thus make it use a different color than PROCESS_HIGH_PRIORITY.

in ncurses. CPU usage goes down noticeably.
(Also, add missing comma, sorry.)

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.

simplify processor data accounting (add CPUData structure)
remove Process_clone trick

Reduces resulting code size.

When user threads are hidden, process now shows the
sum of processor usage for all processors. When user
threads are displayed, each thread shows its own
processor usage, including the root thread.

Also, add option to display thread colors differently.

accurate description. It is still available in
split time, now called detailed CPU time.
