Use getBaseVersion() instead of getVersion() when constructing file paths

Use getBaseVersion() instead of getVersion() when constructing file paths for lib and include directories for nar dependencies. Otherwise Eclipse build configurations will break when a new snapshot of a
dependency is retrieved from a remote repo, because the file paths would have the new snapshot's timestamp in it.

Review is a must on this one. I know it works for me! But I may have made the change in some places where you wouldn't want it. I tried to make the change everywhere I saw that it was generating a file path.
