Remove no-wrap from project/branch fields in ChangeTable(2)

This makes Gerrit very difficult to use on narrow screens, so
allow project names to wrap.

Most installs use project names like "foo/bar/baz" which wraps
nicely at the slash [/]. Spaces [ ] or dashes [-] should also
provide sane wrap points.

Left the classes in place, in case we want to style them in the
future or anyone already had customizations using them.
