[mlpack-git] [mlpack] removing global dependency on cli deleter (#521)

[Ryan Curtin]

When I run `mlpack_allknn` from your branch, the final output is mangled:

```
[DEBUG] Compiled with debugging symbols.
[WARN ] Neither --neighbors_file nor --distances_file is specified, so the nearest neighbor search results will not be saved!

```

I think that this is because the `CLIDeleter` is maybe doing its job too early?  I'm not sure, I will have to dig into it further.  The problem is probably a result of having `CLIDeleter` in a different compilation unit; I'm not sure.  Any thoughts or ideas?  I like the idea of this PR, we just have to make sure output isn't mangled on things that link to mlpack.
