Computer Spike

A new generic lockbreaker has been added, the Computer Spike. Computer Spikes are single use, the are destroyed after use with door lockbreaking.
EDIT: Computer Spike has had its weight/volume/batch size updated to the following values (respectively): 0.5kg / 0.005m³ / 32 per batch. This gives them some advantage over the ELB in that you can carry more spikes than ELBs and in some cases makes them marginally superior to the ELB.

Bugs:
- Some changes to how stun actions are stored.
- Cargo Squads: Added extra checks before starting travel
- Cargo Squads: Fixed UI bug where ordering RTB would not properly clean up squadron
- Cargo Squads: Fixed bug where aborting while loading cargo at a source would leave the squadron stuck once returned to the base
- Due to ongoing reliability issues with periodic jobs, a new status section has been added to the timer status page to show if jobs have successfully run. This will show up after each of the jobs run the next time.
