MOOSE Workflow tree is not populated on Windows

Assigned to Alex. This is kind of his baby.

Interesting find - I just downloaded master latest build, and started ICE in a new workspace, and the workspace path had a space in it. The tree did not load.

I switched to a workspace that had no spaces in the path name, and the tree did load...

Looks like I've found the place to start looking.

Hm. That type of bug normally happens when you are opening a file incorrectly. If you look at the way we open files in Data Structures, that is (usually) the safe way to open files with spaces in the path.

That is to say, it might not be that the view is messed up, but that you aren't actually loading the tree from file at all.

That's what it looks like. Previous implementation of MOOSEModel.createCleanMooseFile is using java nio Files.
