4.1.0
- SCANNING: added caps to rp gained from items (8 per aspect) and added a soft cap on rp gain once your rp pool gets big enough.
- SCANNING: the bonus rp gained from discovering an aspect while scanning is just +2, not double. 
- SCANNING: essentia is also capped at no more than 8 units per aspect type - in the long run it will be better to get essentia from components or raw materials rather than finished products (this has always been true to a lesser degree)
- SCANNING: these caps are configurable
- RESEACH: changed the minigame for research
- RESEACH: "lost" research is being deprecated and rolled into "hidden" research - no point in having both tags
- RESEACH: hidden/lost research applies to more than just golem accessories now. Lost research is hidden in your thaumonomicon until you scan something that gives you a clue to its existence, making it visible and thus selectable. 
- RESEACH: "lost" research can still be gotten via knowledge fragments, but this may change in a future update
- RESEACH: updated the "how to research" entry in the thaumonomicon 
- RESEACH: ditto for the "tubes" research
- RESEACH: tweaked a lot of researches to better fit the new system
- API: numerous additions and changes, some of which will break compatibility
- API: IVisDiscounter is being removed and replaced with IVisDiscountGear. I'm keeping the old one around simply to prevent crashes by addon mods till they get a chance to update, but it won't do anything anymore.
- API: Overlapping research is no longer possible - trying to add research to an already occupied slot will log an error and the research won't be added.
- API: arcane furnace bonus nuggets whitelist has changed to use inputstack instead of resultstack. Blacklist has fallen away
- TUBES: changed the way tubes work so only one type of suction can pass through a tube at a time 
- Arcane furnace nugget production has been reduced a small amount
- Added /thaumcraft (aliases /thaum, /tc) admin console commands to give research and aspects to a player
- aura nodes can recharge even when not chunkloaded  
- changed the components of some aspects
- mana pods now grow very slowly in the wild - lamps of growth are required to get any sort of reasonable speed out of them
- added some AA/blur to certain textures. Thanks Vazkii ;)
- "time zones - how do they work? -- Pahimar"
- foci are now selected from a radial menu
- item grates now count as an inventory and when in the open position items can be piped in from the top to be automatically ejected out the bottom.
- glimmers of light should no longer prevent trees from growing
- angry zombies spawn chances in normal biomes have been reduced considerably
- thaumometer is now much easier to craft making it simpler to get started with TC 
- altered the alembic collision box to be a full block - that should prevent decanting golems from getting stuck on top of the alchemy furnace.
- removed alembic spout and the ability to fill them by placing them below the spout
- jars can now be filled directly from alembics via right-clicking 
- alembics can now be labelled
- fixed research related crash on server when someone adds overlapping research

- hover harness flight is now toggled by pressing "F" instead of double-jump
- added Essentia Resonator to help troubleshoot tube networks (gained as part of initial tube research)
- fiddled with lamp of growth - it should be less essentia hungry and work better
- infusion enchantments should only go where they are supposed to
- most worldgen only occurs in the overworld now - this exludes things that are supposed to be in other dimensions and ores
- infused and amber ores should now be silk-touchable
- added config options to turn certain world-gen features on or off
- devices that draw essentia (like the lamp of growth) only applies suction when they require essentia
- ethereal blooms are a lot more expensive now, but drop the bloom when broken meaning it doesn't have to be recrafted.
- magic mirrors no longer require essentia to function
- split the packet sent to players on login into several smaller packets to prevent a crash bug some people have been experiencing
- removed ability to achieve orbital flight via boats (and other mounts) using sword of the zephyr
- arcane levitator can now levitate items again
- numerous small tweaks, bug fixes and additions
