New tool to list kde-projects dependencies

[Michael Pyne]

Hi all,

I've added a tool (tools/list_dependencies) in kde-build-metadata which you 
can use to verify your changes to the appropriate dependency-
data-$branchGroup. You'd use something like:

tools $ ./list_dependencies frameworks/kf5umbrella

or (to verify dependencies in KDE4):

tools $ ./list_dependencies -g stable-qt4 kde/kdepim

It doesn't look at the branch group stuff in logical-module-structure though 
(but you can and should use the other script in tools/ to verify that).

Remember that with branch groups you shouldn't need to manually specify 
dependencies on a specific branch of a git repo anymore, as long as it's setup 
right in logical-module-structure.

When you get dependencies right, don't forget to commit! ;)
