Pcbnew: Fixed an issue in GERBER file creation, under Vista and W7 only for non administrator users
Plot files were 0 byte length.
This was due to use of function tmpfile() in a GERBER function to create a temporary file that seems not working using mingw.
Replaced by more usual files functions.
* Created separate SVN version header.
* Add true config.h for platform dependency checks.
* Add dependency check cmake module.
* Remove some leftover hand crafted make files.
* Remove non-cmake build instructions from COMPILING.txt.
* Fix split _() strings causing Visual C++ compiler error.
* Fix lots of compiler warnings.
* Change project file parameter container from wxArray to boost::vector_ptr.
* Removed lots of redundant header definitions.
* Fixed green_xpm redefinition in ercgreen.xpm.
* Remove some dead code and unnecessary class methods.
