Cleaning up VDrift source tree

[thelusiv]

Before we do another release, and move the source code to github, we should clean up any unused stuff. Moving time is always a great time to throw out old unwanted junk.

Here's a list of things that haven't been touched in the source tree for a long time, and probably aren't used or aren't necessary any longer:

• binaries/ - 19 months old - only contains a very old linux 32-bit binary
  
• docs/ - 2 years old - this is sort of a separate topic, but this should probably just be replaced with a README.txt file that tells users to visit the wiki for now, until we get some way to generate full (current!) docs from the wiki, or something like that.
  
• po/ - 2 years old - we are using a new type of internationalization now, this is no longer needed, the SCons build support has been removed.
  
• VDrift.kdevelop* - 19+ months - Joe has stated he no longer uses KDevelop, so these are no longer being maintained.
  
• gpl.txt - change to LICENSE.txt?
  
• Doxyfile - should go in tools/?
  
• grind - should go in tools/?
  
• tools/anjuta/ - 2 years old - same as kdevelop stuff
  
• tools/autopackage/ - 2 years old - not going to use this anymore, Autopackage is defunct
  
• tools/cars/ - 2 years old - this contains an empty .car file which is really old and probably wrong. it would be better to have in the VDrift-art tools/ dir, or better yet, to write a generator script that uses a file like this as a template to create a blank car with some values filled in.
  
• tools/debian/ - 2 years old - this is old, however could be updated with some information someone posted here: http://wiki.vdrift.net/Talk:Compiling#Bu...B_packages

There are probably other things to clean up, but those are most obviously old and unused.

Please post how you feel about these changes. If you feel something in the list needs to stay where it is, please include a simple explanation why.
