Align kwarg lists

[adzenith]

(This is based on top of #35, so just look at the last commit. I can rebase if you like.)

This adds a config option to align lists of arguments across kwargs. It turns this:

          HEADERS a.h
                  b.h
                  c.h
                  d.h
                  e.h
                  f.h
          SOURCES a.cc b.cc d.cc
          LONG_KWARG foo bar baz)

into this:

          HEADERS    a.h
                     b.h
                     c.h
                     d.h
                     e.h
                     f.h
          SOURCES    a.cc b.cc d.cc
          LONG_KWARG foo bar baz)

It also interacts correctly with #35 if you want something like this:

          HEADERS
                    a.h
                    b.h
                    c.h
                    d.h
                    e.h
                    f.h
          SOURCES
                    a.cc b.cc d.cc
          LONG_KWARG
                    foo bar baz)

I like the idea of supporting this, but I'll have to think about how to properly implement with the overhauled formatting logic.

It's been a long time since I've commented on this PR but I just wanted to mention that it's still on my queue. I think that there are definitely some cases where it makes a lot of sense e.g. ExternalProject_Add. Personally I don't think I would want it to apply all the time, so I'm thinking about the different config options to enable this. I will hopefully address this feature soon.
