Make quality repair packs repair faster

[Iridium-235]

Currently quality repair packs only have greater durability, which isn't that useful, especially since by the time you have quality repair packs you already have more than enough resources to mass-produce them, and their stack size is very high which makes durability even more redundant.

Instead, what if repair packs had repair speed boosted by quality? This would be useful and give your more reasons to invest in it.

For example, after attacking a biter base, your turrets/vehicle would be damaged. Repairing them manually with normal repair packs takes a long time, so using quality variants would be much better and less tedious.
