Ensures all parts of the Electron have a fully-defined initial state.

Specifically to resolve an error with shift being pressed at startup due to a failure to establish a default value for that flag, but applying the same principle across the board.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Resolved spurious static analyser issue; screen mode will always be 0–6 but it doesn't know that. Setting a non-zero divider doesn't feel worth worrying about for a cleaner compile.
