Buildsystem switched to gyp and updated to v8 4.2

[ReneHollander]

I just wanted to put this pull request out there. It's not completely finished yet but it should be a solid base for future work. Here is a list of things that still need to be done:

• Update to even newer v8 version
• Finish new library loader
• Finalize build script to handle publishing of build artifacts

Here are some things I changed:

• Switched to gyp as a build system to allow for better integration of newer v8 versions
• Improved library loader to handle different versions of the library
• Switched to Gradle as a build system because it allows for better automation of the build (The gradle script also handles building of the native code. Use ./gradlew native_ to build)
• I mainly tested building on Linux, but Windows and Mac worked. Android builds are also possible

Sidenote: I cloned the io.js repository and removed all io.js related code and just added the two source files of this project. This was not only really easy, but every version of v8 should work. Just copy the source files into native/deps/v8 and compile it. If this doesn't work just copy the deps/v8 directory of io.js into the directory and it should work.

Something to mention: The native part should compile on every platform v8 compiles on without any changes to the build files. Only a shell script in native/ has to be added and the Gradle script needs another task. If the library loader doesn't already have the code to detect the operating system it should be simple to add.

Wow! Thanks. I'll take a look at this later tonight or tomorrow!
