Implement Dynamic Handler Height

[slprime]

Example:

[Ranzuu]

This needs to be re-opened or some fix needs to be added. Because of that PR all of the NEI backgrounds are misaligned, there were already some fixes for the GT NEI pages, but not in other (all of them) mods.

• Fix transparency border #838
• Move Background in NEI Handlers GT5-Unofficial#5572
• Move Background in NEI Handlers and remove the recipe buttons from Space Pumping Module and Planetary Gas Siphon GT5-Unofficial#5728 (not gonna do that)

and it won't be nice to literally edit some numbers on every mod + have some NEI pages not aligned because of ARR mods.
