Raise max transfer capacity on bottles from 30u to 50u

[truls20]

Currently bottles, specifically ones from chemmasters, have a capacity ranging from 5u to 50u. Their transfer capacity is 30u at its highest, this stands in stark contrast to every other chemical container that have identical max capacities and max transfer capacities.

I believe it will improve the game if we right this historic wrong, and finally establish a real precedent of max transfer capacity being identical to max capacity for any chem container!

Sounds like a good idea!
