Fixes of some basic important features

 * Implicit include paths
 * Delayed include paths
 * Inclusion of .d-files for submodules

Clean up and performance improvements

=== Note
Using less conditional assigments improves start-up and processes launch
(clone) significantly resulting in ~25% increased peformance. For projects
having large amounts of makerules.mk files (+300) in multiple sub-directories
the increase is >60%.

At this point Bob is ~10% faster then Scons building a C/C++ test project
consisting of 5 target spread over 100 source files, and utilizes only <20% of
the amount of stat calls that Scons requires.

Performance improvement

 * Calling bash without running profile files.

Have most stuff in place.

 * Cleaned stuff to get less.
 * Removed unsued features, tagging and branch help e.g.
 * Applied patches from internal version.

First usable after rework.

 * Wildcard for source files in a "different way"
 * Removed a lot of guff.
 * Only 'setup' instead of 'setup_requires' (less spelling errors).

Major rework begun
