Tweaks and ReStock(Plus) support

[Vladimir-csp]

Hi! I've goofed around with the configs a bit. Summary:

Stock:

• Rebalanced Reliant and Swivel
• Normalized Spark and Twitch to use OMS-Red, Ant and Spider to use OMS-White
• Rebalanced SRBs (There is still something wrong with Flea and Hammer, looks like stock plume is not overridden)

ReStock:

• Added tweaks for ReStock
• Added support for ReStockPlus
• (ReStock* stuff requires a new dirty plume to put on turbopump exhausts)
• (No patches for RAPIER and Vector yet, need help)

• ReStock and ReStock+ support will not be implemented until it gets a first release.

• Tweaks to stock configs will be implemented in a later release.
