ProjectExplorer: Add convenience accessors to some classes

Namely, Kit, BuildConfiguration, BuildSystem and RunConfiguration get
functions to retrieve the active instance for a given project as well as
the one for the current and active projects, respectively.
This saves a ton of annoying null pointer checks.
Some of these functions replace existing ones with the same purpose that
were scattered around the code base.
