[Feature Request] Backport REI Collapsed Block Subtype Selector

[Polarite]

IIRC REI has a feature that makes same item types like colored glass, wool etc collapse in a single slot and open up when you click on them, similar to recipe book. Implementing this feature to NEI would not only decrease at least 30% of NEI pages, also make NEI easier to use.

also useful for microblocks for example

In case someone decides to do this, please check that it does not collapse stuff like metaitems into one section.
