[Vala] Vala Dependency Scanner

[Michael Terry <mike mterry name>]

Hello!  I was recently helping create a Vala template for the Quickly
program (which is just a quick and easy way to create/share/package
projects: https://launchpad.net/quickly).  Anyway, along the way we
realized it would be great if we didn't have to ask the programmer for
the list of vapi dependencies their program required.

So I thought about it a bit and came up with vala-dep-scanner, which
will parse a set of files and tell you which vapi files it uses
symbols from.  That way you can automatically create a list of
dependencies to build with.  I'm not sure how useful it is outside of
the Quickly context, but I thought I'd bring it up here in case others
were interested.

It works fine for the code I've thrown it at, but bug reports welcome.
 It also lacks some features like Genie support and such.
