on Darwin, htop needs to run with root privileges to display information
about other users processes. This commit makes running htop SUID root a
bit more safe.

Closes #228.

Fixes building on case-insensitive filesystems where String.h gets confused with <string.h>.

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

Add a setting to hide all but the last component from the programme
path, leaving only the "basename". Makes htop more usable on smaller
screens, or systems with longer than average paths. Off by default.

"Highlight program basename" will still be respected, to further
visually separate process names from their arguments.

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

Patch from ArchLinux. Closes #65.

For now rates won't be colored gray when zero; I'll think about that.

On my machine, this gives a ~20% improvement in htop process time use with the default config.
