Included code to read the xml file and draw the corresponding instrument.

Hud.hxx, Hud_ladr.cxx, Hud_card.cxx and Hud_labl.cxx
---------------------------------------------------
Integrated code to draw any kind of hud.

Preference.xml
---------------
Included XML file path in the sim/hud property.

ReadMe.xmlhud
-------------
The Readme.xmlhud describes the reconfigurable HUD implemented thru XML
files.
