<span> and cable use()

- Added more span tags
- using cable now uses use()
- fixed use() to correctly return 1 when it succeeds
- checked that there were no checks that would’ve been previously
borked. For testing purposes I renamed use to use_cable (‘use’ is kinda
bad for a proc name, but use_cable is hardly better), but left that out
of the commit because it would’ve inflated the pr.
