Title: Support for debug builds (concatenation only)

Whitespace builds are still painful to debug. Skipping the compiler altogether and simply concatenating sources is a better option for development and debugging. By ommitting the `compile` option in a build config, the output is "uncompiled" - a straight concatenation of all sources in dependency order.
