Library changes

I've just made a final (I hope) tweak to the "lib" rule. Now it's possible to 
do

lib png : z : <name>png ;
lib z : : <name>z ;

or 

lib png : z : <file>png.a ;
lib z : : <file>z.a ;

and if you link to 'png', the 'z' library will be picked up too. Previously, 
this required non-intuitive syntax.

At the same time, the prebuilt.jam module which used to implement <file> was 
removed. The <file> feature now works only for "lib" targets, and you should 
use "alias" in other cases.

Finally, I've expanded the documentation on libraries (and other builtin 
rules):

http://boost.org/boost-build2/doc/html/bbv2.advanced.builtins.targets.html

Bug reports are welcome.
