Capture all signals and improve code

[dasJ]

Changes:

• Catch all signals
• Only run gcc when target is not up to date
• Fix some minor code style issues
• Reformat all debug output

I think this is mostly what #1 does, but it does not break the tests.

Hi! Thanks for taking the time to put this together.

A few questions, is there a reason for handling the duplicate signals? I preferred documenting the duplication in the comments.

Also, for the comment about SIGCHLD which you removed, I just realized I mistakenly say I should not proxy it, but still do. I need to write some tests for that, but the behaviour seems bad. This is mostly a note to self, but thanks for helping me see it :)

P.S. Sorry for the slow response, i've been somewhat busy these days

Well I expected #1 to be good and just lacking the tests. So I did basically the same but with tests. If you want me to rebase out 7250071 to merge this, I can do so.

Super! Just drop 7250071 and i'll merge this in.

Thanks,
R.
