application always run from root directory

val p = project {
 ...
}

val example = project(p) {
    name = "example"
    directory = "example"
    ...
    application {
        mainClass = "com.example.foo"
    }
}

./kobaltw example:run will execute from the root directory, not directory.

This will be even more important if Kobalt is to support multiple build files.

Probably related to #273

Yes, you just need to launch it in a separate process. I can modify run to do that.
