project.cfg: remove COMPONENTS and SUBPROJECTS lists from [PROJECT] section and use explicit sections for components

[Alexander Belchenko]

E.g.

[PROJECT]
...

[component "foo"]
BRANCHES = trunk dev

  [[branch "dev"]]

[subproject "spam"]
...

In this case PROJECT section could be optional too.

Is there a reason why we have to quote the element names?
I think we can make the quoting optional or just not quote it.
eg.
[component foo]

Well, it was designed after git modules format.

Perhaps we can omit quotes. I'm just found quotes easier to parse.
From other hand I've used very strict regex and allow only ASCII-alpha chars,
digits and minus and underscore signs. So quotes are not strictly needed
because space sign is not allowed.

I don't have strict opinion on this topic yet. Do you want to implement it?

OK, thinking further I'd say quotes should be optional but supported.

I'll change this.

The code itself is almost ready to use, need to update the docs.
