MSVC project files update

[eipi]

This patch provides an update to the MSVC 2010 project files (as of r5830).
What has been changed:

• The executable file is put into ./simutrans in both configurations.
• The names of the executables in Debug and Release mode are now simutrans-trunk-dbg and simutrans-trunk, respectively, in order to avoid overwriting upon build
• Libraries are taken from ./libs/win32
• Mulicore processor compilation and floating point exceptions have been enabled in Debug mode
• Updated the revision number to the current version
• Added some missing native library dependencies

Any further suggestions are welcome

I will do a new project file, the current VC2010 is not useful (no header, absolute path for libs, not svn code, ... )
