edf1b10d2c Read CPU frequency from sysfs by default 
Use the more portable sysfs node /sys/devices/system/cpu/cpuX/cpufreq/scaling_cur_freq
to get the CPU frequency.
In case of an error fall back to /proc/cpuinfo .

Also use a fixed width of 4 for the frequency to avoid position jumps
in case the frequency moves in the range 900-1100 MHz.

f4bb50294a show selected command wrapped in a separate window 
For a process with a very long command, especially with many long
command line arguments, inspecting the command and its arguments could
become inconvenient.

Meanwhile htop supports the concept of "screen", or window, which is
extended here to create a dedicated "CommandScreen", making it possible
to display the command of the selected process in a separate window
meanwhile being wrapped into multiple lines.

Another benefit of using a command screen is, the user can navigate
through the wrapped lines of the command and perform actions like
searching and filtering.

5233817122 Avoid unsigned integer overflow 
unsigned integer overflows are well-defined, but they might point to a counting issue.
Having the code free of unsigned overflows makes it easier to spot potential bugs.

  Action.c:332:27: runtime error: implicit conversion from type 'int' of value -1 (32-bit, signed) to type 'uid_t' (aka 'unsigned int') changed the value to 4294967295 (32-bit, unsigned)

1061bd719a Change option '-m' to '-M' for consistency of cli 
`-m` was added as short option for `--no-mouse`, this is inconsistence
to the rest of the cli since otherwise the short options to disable a
feature are capital letters. Therefore this commit renames the option to
`-M`.

This commit also documents the option in the man page.
