File System implementation in the Script Language

The script language shall be able to access the virtual file system thanks to a Path object, allowing for the manipulation of path, directory exploration, directory creation, etc... And a File object allowing for the manipulation of the content of a file.

When loading the features into the AngelScript engine, it was planned to register the Path object with a special factory function : this factory function was supposed to bind the VirtualFileSystem object to the constructor of the Path so that it can directly be used like Path("file.txt"). Sadly, doing so require a capturing lambda function (std::bind work the same way), which cannot be converted into a function pointer, which AngelScript use internally.

A new type, FileSystem, have been created for this occasion. It cannot be instantiated, but a global variable fileSystem allow for accessing a Path thanks to the FileSystem::getPath function.

Path have been implemented with most of the required functionalities, alongside File with read and write capacities. More advanced features will be implemented later, like text handling with potential encoding support or Path manipulation with withSuffix or withBasename functions.
