latex format fails to copy external directory

[StevenClontz]

To replicate:

pretext new
cd new-pretext-project
mkdir assets
touch assets/foo.txt
pretext build print-latex # no external directory is copied!

I looked back and found where we used to handle this:

pretext-cli/pretext/project.py

Line 410 in 3bb3b6b

# core script doesn't put a copy of images in output for latex builds, so we do it instead here

I guess maybe this got forgotten in the 2.0 refactor? Though I'm unclear why generated is being copied but external is not.

For posterity: I don't think generated was being copied, actually.

It looks like we should manage directories in the CLI. Should this also be done for the custom target???

Yeah, I think we should run core.get_managed_directories and core.manage_directories (once it exists) to put files where our users will expect them.
