Support xterm OSC sequences for text and cursor colours

[GoogleCodeExporter]

MinTTY should support the OSC sequences for changing text and cursor
colours. From http://invisible-island.net/xterm/ctlseqs/ctlseqs.html:

OSC P s ; P t ST
OSC P s ; P t BEL
  ...
  P s = 1 0 → Change VT100 text foreground color to P t
  P s = 1 1 → Change VT100 text background color to P t
  P s = 1 2 → Change text cursor color to P t

Also, the 'P s = 4' sequence support should be extended to be able to
change all 256 xterm colours.
