Bring back the 3xHotKeys sets, Increase active mutation cap to 5 & Active Mutations bug when loading back in

[TheWhiskDad]

I'm not sure if any of these have already been discusses or not but two things that I really wanted back from Grounded 1 are the following:
1) In Grounded 1 we had 3 sets of HotKeys we can put items into and scroll between each set. So we could have a total of 24 bound items. I struggled a bit in Grounded 2 because there are so many items that I would like to use or weapons to switch in and out of mid battle and its a but cumbersome to go into the inventory mid battle. 
2) Max mutations we could equip back in grounded 1 was 5 and its 4 here. Not sure if this is intentional for the time being and this will eventually be brought back up to 5 when more mutations are added but even now I always feel like i'm lacking one crucial mutation for my build or in any given situation while playing. Felt like 5 max active mutations was the ideal number.
3) Finally there is a bug where when loading back into a save, our equipped active mutations are back to 2 and we need to re-equip back the mutations. This is fine but at times when there are constant crashes , this becomes annoying.
