Standardize Scripts

[rajadain]

In many of our new projects we run scripts from within Vagrant. Some scripts in this project are to be run from inside, while some from outside. Pick one and standardize to it.

Context from #2:

In an effort to minimize the difference during import, I've tried to keep the scripts consistent with what they were in Model My Watershed. However, they are now inconsistent with all our other projects which run scripts from within the VM, rather than from outside. I'm making cards to address this in the future.

Also consider removing the --vendor flag, and making that behavior standard:

We probably don't need the --vendor flag in the bundling script anymore. That is also a holdover from Model My Watershed and should be removed.
