[Boost-build] Changes in --clean option

Hi!
I've comitted a change to the way --clean option works. Previously, it would 
clean all targets Boost.Build knows about -- including changes under 
different Jamroots, which was pretty confusing.

Now:

1.
     bjam --clean 

removes only targets from the current Jamfile and its direct and indirect 
children. Targets having different Jamroot, and targets in parent Jamfiles 
are not removed.

2.  bjam --clean some_dir

removes only targets from some_dir/Jamfile and its direct and indirect 
children. If there are two subdirs: sub1 and sub2, and sub1 referes to 
targets in sub2, and you run:

   bjam --clean sub1

the targets in sub2 are *not* removed.

The new --clean-all option has the old behaviour: cleaning absolutely 
everything.

I know some people were interested in such change. Comments appreciated!
