FlightGear - Flight Simulator FGAddon

A number of fixes to the livery system, improve the textures a bit, add livery support for leather and logo's, add prop and engine disks for higher rpm's, fix some colouring, fix a name and add adjustability for altimeter.

Rework the cockpit to beter reflect what is supposed to be original: http://oesau.org/images/ROF/Fokker-Dr,1-Cockpit-1.jpg

FGAddon repository optimisation, elimination of svn:mime-type on all XML files.

This follows from the proposal at
http://thread.gmane.org/gmane.games.flightgear.devel/77365 and the discussions
at http://thread.gmane.org/gmane.games.flightgear.devel/77270.

As the svn:mime-type value of "application/xml" is designed to treat text files
as binary files, now all XML files in the FGAddon repository will now be treated
as text instead. This will minimise the size of the db/revs/* svn back-end
files when changes occur, minimising the strain on the SourceForge
infrastructure.

Aircraft affected by this change are: 777, A6M2, airwaveXtreme150, AR-234,
Arsenal-VG33, ASK13, ASK21-MI, B-17, b1900d, Beechcraft-C18S, Bernard-HV220,

bo105: With permission by original authors, Curtis Olson and Torsten Dreyer I'm now taking care of the bo105: Adding Status Rating, catalog metadata and ReadMe-File today

Move cockpit related files to their own directory, fix some gauges and add a functional fuel gauge and watch

Citation II:

* change starter animations, so that /controls/engines/engine/starter
would not jump to false, when keypress is gone. Rather stay true
until spool up is complete.
* add igniter indicators on electric panel

Citation II:

* changed all system to use new bus properties
* added starter knob light, when engaged
* added starter disengage function

Citation II:

* add noise-spike filter to volt-meter (make changes gradual)

Citation II:

* enable voltmeter on electric panel
* repair fuel boost pumps switches and their functionality
This is a temporary fix, until a more sophisticated fuel management
system is in place
* make battery switch 3-way, enabling to only power emergency bus
(EMER) or power emergency bus and battery bus (BATT)

Citation II:

* add needles for voltmeter and amp-meter on electric panel
* make fuel boost switch 3-way
=> controls/fuel/tank/fuel-boost-switch
which means manual start up is broken until this is refactored
again
