Hello!

The main refactoring is now done. I went a bit differently then I originally stated, as it somehow flown out out of the box
 * all 4 tools now prints to stdout by default
 * all 4 tools now support -d <dir>
 * the dual stream logger is still the default one

Is it ok for you to start playing with it?

if not, then I will most likely go with the commit, which will return jasm and jcoder back to origianl "-d like" behavior by default, and have stdout only as secondary option - Still I think the current state, all 4 stdouting and honoring -d is better

In all cases, there are at lease still two commits pending
 - made dual stream logger on deman only (otherwise be on single stream stderr logger only)
   - if the single stream logger goes really well, then drop the dualstream, as it is confusing
   -  if there was not those nasty printlns/printlne, I would vote for keeping the dual loger as optional extension, as the original logging have it sense. But it may rot on long term
 -  prepare string and streeam based stdotu/stderr and add more tests; that will most likely lead to small clean up
