Top level config option to log command-line for eclipse to parse... default off

NOTE! This is half the change, will send another request for nar-maven-plugin based on whats already in my fork...

I found myself running by builds with -X in eclipse, just to get the CDT behavior I have come to expect. As long as the extensive logging didn't overrun the Console buffers I got my code-completion and navigations (F3) back.

However I decided to attempt to make nar-maven.plugin log the command-lines with less fuzz.
After a brief interaction with Johannes Schindelin I choose to make a top-level config option commandLog
that is default false. If set to true the command-lines only are lifted from DEBUG-level to INFO.

I have been using this for a couple of hours and it works like a charm and eclipse CDT is delivering again.

I hope to get this into mainstream since it is a quite simple addition and very usefull to anyone using CDT.
