Toolsets init updated

The second round of toolset initialization cleanup affected borland, msvc and 
darwin.

Now all toolsets has the same initialization syntax

init ( version ? : command ? )

If tested borland and msvc locally, but in case there's some fallout from my 
changes, let me know. For users the change means that instead of

using msvc : 7.1 : some_path ;

you have to use

using msvc : 7.1 : some_path/bin/cl.exe ;

There's one toolset I did not touched -- kylix, because I'm not even sure it 
works? Anybody has any experience with using kylix with V2?

I've also did not touch tools which are not compilers -- like bison and lex. 
Probably that's for later.
