ProjectExplorer: Add an official way to connect aspects

Aspects are not completely orthogonal, e.g. working directory
depends usually on environment etc. So far handling this used
ad-hoc set up in the (Run)Configuration constructor. Lets make
this an official second phase, that also reduces the need to
use a specific construction order of aspects.
