Subject: [PATCH] Removed cloning a specific revision from the mercurial
 download strategy.

When cloning a mercurial repository from a tagged revision, that tag definition
isn't actually included. This causes `hg archive -r tag_name` to fail.

Instead, just clone the repository's head and the `hg archive -r revision` will
handle getting the correct revision to for the build
