Make dependency properties specified in project requirements

not cause errors in subprojects.

* build/property.jam
  (tranlate-dependencies) New rule to bind dependency
  properties to the project that they are specified in.

* build/property-set.jam
  (create-from-user-input) Add call to property.translate-dependencies

* test/test_all.py test/inherited_dependency.py
  Test case for this fix.
