Refactor naming of SpaceViewClass and changed TextSpaceView name …

…to "Text Log" (#4386)

### What

Space View names are now user-facing, so I wanted to change "TextLog" to
"Text Log", consistent with all other multi-word space view names. In
the process, I ended up refactoring the way names is handled for
`SpaceViewClass`s ~~and `ViewSystem`s~~, such that they all provide a
convenient `ClassName::NAME` constant to use throughout the code.
