Feature/ltsv all things

Use LTSV logging instead of not or doing it everywhere via Logger.<level>(LTSV.dump).
One way would be to check if debug is enabled before calling the method, or, giving up on varargs (and thus uglify code a bit) to use call-by-name params.

That said, call-by-name (and it's cousin, lazy), isn't free either from a performance perspective.
