Subject: [reltool] Add configuration parameter lib_dir on application level

As a way of specifying one specific version of an application, the
following configuration parameter is added on application level:

{lib_dir,Dir}, Dir = string()

This can be useful if the parent directory of the application
directory is not suitable to use as a lib dir on system level.
