Remove spaces from directory names

[michaeleisel]

Beam has a fantastic code base for testing tools at scale. There aren't many open-source apps of that size. However, it breaks tools like https://github.com/peripheryapp/periphery when there's a space in a source code directory name, e.g. Beam/UI/Generic UI. It would be great for all the spaces to be removed.

Shouldn't tools support spaces in file/directory paths instead?

The reality is that they often don't. It also breaks any scripts that don't remember to put quotes around a path, any time someone copy-pastes into the shell without any added escaping, etc.
