Subject: [PATCH] It is possible to set an "install-dir" option for a package
 now

This let's you completely customize the path needed for your custom
package. So you can specify paths directly on top level and are not forced
to install your packages under the vendor/ directory.

Example:

{
    "name": "my-project",
    "version": "1.0.0",
    "repositories": {
        "MyRepo": {
            "package": {
                "name": "mypackage",
                "version": "1.0",
                "install-dir": "lib/src/mypackage"
                "source": {
                    "url": "https://github.com/awesomepackages/mypackage.git",
                    "type": "git",
                    "reference": "some-tag"
                }
            }
        }
    },
    "require": {
        "mypackage" : "1.0"
    }
}
