implemented dynamic patchouli page.

what's the difference between ModLoadingContext and FMLJavaModLoadingContext ???

• add convertion ratio config file for linker items

• add conversion ratio display in item tooltip

• heavily nerf their default ratios to match the OPness of Hex, not Ars :(

猛削了初始数值，但是可配置了。

Added Patchouli entry for both guide books
