Configurability improvements, mainly for AE2 FC

[PukPukov]

• Add configuration for "non-condensable" items to resolve Ban drops from Matter Condenser AE2FluidCraft-Rework#179
• • Some items and fluids can be selected as "non-condensable", as a result they will not produce matter condenser power.
• • This will not excessively break existing setups because matter condenser will still allow input of everything, just some items now will simply disappear
• Initial implementation of stack size fixer
• • Some externally added item count scales can not align with native item count scales and therefore spam terminals in by-count sorting mode. A first-class example would be AE2 FC drops, when you add 1 bucket and instantly every type with less then 1000 items is behind this single bucket of drops.
• • A solution is to add config to manually scale item types. The default config scales drops by the factor of 1000, so 30 stone blocks will be equal to 30 buckets of water represented in drops.
• • Currently this does not change amount selection guis (crafting, level emitter), but this is planned
