add game textures link and reword intro
This is supposed to eventually become a directory of 4D-modelling related resources (i.e. 3D models, textures, images, sounds etc.) that are freely available on the internet.
: while many webpages offer indeed free download and use of such files, it may be necessary (and is indeed recommended ) to explicitly ask the individual copyright holders for their permission to include their work within FlightGear related materials that are supposed to be publicly made available and possibly even released under the GPL, in order to be eligible to become part of the FlightGear base package (any files that are not officially GPL'ed, cannot become part of the official FlightGear distribution but need to be distributed separately).
