Added a new format for displaying an array of characters: eFormatCharArray

This us useful because sometomes you have to show a single character as: 'a'
(using eFormatChar) and other times you might have an array of single 
charcters for display as: 'a' 'b' 'c', and other times you might want to 
show the contents of buffer of characters that can contain non printable
chars: "\0\x22\n123". 

This also fixes an issue that currently happens when you have a single character
C string (const char *a = "a"; or char b[1] = { 'b' };) that was being output
as "'a'" incorrectly due to the way the eFormatChar format output worked.
