Fixes for mods that failed quietly during loading.

• Biomes O' Plenty: its versions of the vanilla biomes (forest, desert, birch forest...) failed to build, because a 1.7.10 biome method had the wrong shape in our API. BoP left 29 vanilla biomes empty, which then broke other mods.
• Tinkers' Construct world generation (ores, oreberries, slime islands) was not set up at all in packs with Biomes O' Plenty, because of the empty biomes above. It works again.
• Applied Energistics 2 with ForgeMultipart: AE2 builds its cable classes at load time. That failed before ("Error loading ...ISidedInventory"), and now works. CodeChickenLib can also read the game's interfaces again to build multipart traits (#21).
• Block renderers asking for smooth lighting (isAmbientOcclusionEnabled, 10 calls in the test set) no longer throw; the answer follows the video setting.
• Witchery doors: two door helpers had the wrong shape.
• The translator now catches this kind of mistake (a static method where mods expect an instance one, or the other way round). Such calls link to a placeholder and are listed in the report instead of crashing. No such calls are left in the 1.7.10 and 1.12.2 test sets or the 100-mod test pack.

Also includes everything from 0.2.10.
