Cleanup module dependencies: a lot of modules depended on 'frontend.java' just
to use something from 'util' module, exported by 'frontend.java', whereas they
really need nothing from 'frontend.java'. Also 'frontend.java' just exported
'util', not using anything from it.
Create a new 'util.runtime' module, which will be available at runtime. Make
'util' export 'util.runtime' and make all modules who needed these utils depend
on 'util' directly instead of 'frontend.java'
Major changes: ASM is switched from vanilla 3.3 to a 4.0 with renamed packages,
because this is done inside IDEA and we depend on that transitively.
Thus the jarjar renaming in build.xml, old library binaries deleted.
Also we now depend on exact IDEA build (EAP), not "last successful".
