Feature Request: Scalable Raid Protection

If I should have done this in Discussion area let me know... and my apologies. It's not an issue I have, but a feature request that I think would be a great addition if possible.

Plugin the way it is, great ... wouldn't change any of the existing options, I would just like to see a new one. Which is scalable raid protection. If enabled via config, it would display in the TC Protection TAB " 20%, 40%, 60%, 80%, 100%" ... as buttons. Player picks one and it uses scrap in TC to provide that level. If player changes it to say 100% then it would obviously cost a lot more ... so scrap requirement would need to scale up as well. This makes it so players while they're broke can still apply something like 20% for however much time that provides and as they grind and accumulate more scrap they can up the % level ... costing more, forcing them to grind harder etc. 

Thinking it's just a great way for players to work they're way up to 100% ... however, maybe in config give server owners ability to remove the 100% option if they don't want 100% to be available. 

What you think?
