Opt out of implicit -T

[jglick]

I am not sure how I feel about the implicit -T argument being added by default, but there should at least be a user setting to disable it by default (without adding -T1 to every invocation):

• Principle of least surprise. It should be possible to use mvnd as a drop-in replacement for mvn with as few risks as possible. Parallelized builds are not enabled by default in Maven, so if there are problems in mojos or POMs which are manifested only in this mode, it would effectively look like a bug in mvnd.
• The dynamic console output was apparently invented with -T as the motivating use case, and there are reasons to not want it, as in Option to default to a simple log when using a single thread #116.

#176 will allow storing your -T preference in ~/.m2/mvnd.properties:

mvnd.threads = 1

Good to have a config option for this!

What if a certain project cannot be built multi-threaded? I guess in this case one has to resort to passing -T1 for each run?

Yes, currently, there is no better option.

If you mean that we should have a per-project config file, feel free to create a new issue.
