easier regression handling - makefile
It's a bit tedious to change to the regression dir to check regressions.
The attached diff adds a Makefile in the main dir which calls the Makefile in the regression dir. Additionally it defines targets install and bundle which call setup.py and bootstrap.py respectively
Sensible to include such stub Makefile? Should bundle do more? Like try to build the windows exe? Is setup.py and bootstrap.py the 'sane' choice for those targets or is there something more suitable?
Add #3202: Makefile in the root dir with targets 'regression'(='test'), install and bundle
