Warn if program/library/data is defined multiple times

[Robert Ancell]

Warn if program/library/data is defined multiple times, i.e. programs.foo.* is defined in src/Recipe othersrc/Recipe.

It's probably better to limit IDs to the same file to reduce confusion.

It could be good to allow programs.foo and libraries.foo in the same project (each only once), if the program foo is one of the programs in the project linking against libfoo.

[Robert Ancell (robert-ancell)]

Agreed, programs and libraries are in their own namespaces. Bake should stop being able to have two foo programs or two bar libraries though (otherwise you can't unambigiously link to a library inside your project).
