Proper support of Windows Phone 7 and Silverlight 4.

KopiLua does not support Windows Phone 7 out of the box, due to several issues that are fixed in this release:

- Incomplete KopiLua-wp7 project file does not compile (lnet.cs is missing).
- Bytecode loading is invalid (lundump.cs uses unavailable Marshal methods).

Besides fixing these issues, thus providing the first library that can run Lua on Windows Phone 7, this release also fixes line-ending normalization for the repository.
