Toggle button to select whether to use a Skill

For those specific skills that decrease cost (e.g. Expedited Repairs) or increase pay (e.g. Winning Compromise), we should have a toggle to choose whether to use the skill at this time.

Examples:

• If I only have 1-3 damaged ship components, I won't want to use Expedited Repairs — much better to save it for post-battle when there are major repairs required.
  
• If I just need a local One-way Shipment run to get enough creds for that upgrade I want, I'll want to save Winning Compromise for my next multi-step mission a few hyperwarps away.

Thanks for the feedback. Some of these talents, such as Expedited Repairs, are going to get minimum values, like the Big Trade Talents which only kick in if you make a trade over $5,000.

Awesome!
