+ansistatuscolors
+by la11111
+
+updated 11.12.12 - squashed my code together to
+patch better across versions - killed remaining memory
+leaks. removed some useless junk.
+
+put ansi escape codes in your status bar output to
+change the color. Note: full ansi spec not implemented
+at the moment. incorrect codes are ignored, even if they
+may be valid ansi codes (ie, changing up the order or something)
+
+*** escape code format:
+
+\e[<code>m
+
+ \e - ascii 27, hex 0x1b, octal 033
+ [ - literal bracket
+ m - literal 'm'
+
+*** codes supported:
+
+standard escape codes:
+
+n;m
+ n -
+ 0 - normal
+ 1 - 'bright'
+ m -
+ 30-37 - text foreground
+ 40-47 - text background
+
+0 -
+ reset formatting to default
+
+example (python):
+ print "\x1b[1;31mHello World!\x1b[0m"
+
+256-color escape codes (xterm):
+
+n;5;m
+ n -
+ 38 - text foreground
+ 48 - text background
+ m -
+ 0-15 - alias classic ansi colors
+ 16-231 - rgb grid color
+ 232-255 - grayscale ramp color
+
+example (python):
+ print "\x1b[38;5;196mHello World!\x1b[0m"
