* apps/netutils/webserver/httpd.c: Add support for Keep-alive connections
(from Kate).
* apps/NxWidget/Kconfig: This is a kludge. I created this NxWidgets
directory that ONLY contains Kconfig. NxWidgets does not like in
either the nuttx/ or the apps/ source trees. This kludge makes it
possible to configure NxWidgets/NxWM without too much trouble (with
the tradeoff being a kind ugly structure and some maintenance issues).

apps/NxWidgets README File
==========================
The NxWidgets and NxWM libraries don't physically reside in the apps/ source
tree. The source code actually resides at the top level NxWidgets/
directory. This directory is just a kludge...it is here only support
configuration of NxWidgets and NxWM.
The only files that reside in this directory are (1) this README.txt file
and (2) the Kconfig file to support NxWidgets configuration. This is a
duplicate of the NxWidgets file that you can file at NxWidgets/Kconfig.

* configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not
have an SSD1289 controller. Its an ILI93xx. Ported the
STM3240G-EVAL ILI93xx driver to work on the Shenzhou board.
* configs/shenzhou/nxwm: Added an NxWM configuratino for the
Shenzhou board. This is untested on initial check-in. It will
be used to verify the Shenzhou LCD driver (and eventually the
touchscreen driver).
* configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen
support for the Shenzhou board. The initial check-in is untested
and basically a clone of the the touchscreen support fro the SAM-3U.
