Phlegethon Tunnel Sounds.  Rework of ICryogenCore.  ResearchManager improvements.
WorldLocation now supports hashing.  Start of own sound manager (to enable stopping running sounds)
Switch PhlegethonTunnels to regular sound.  Made SoundManager client-side only.  Femtocraft Sound Manager needs a packet system, to know to start playing sounds, and also to know to listen for them with the forge event bus.
Stopping playing sounds seems to work.  Looping didn't work as well, due to inability to detect client-side leaving a game or switching dimensions.
It's not perfect, but the sound manager gets the job done.  It's capable of stopping sounds early, as well as telling clients to stop playing sounds from Femtocraft when the user switches dimensions (but not when they log out, by the time the event is called the player has already disconnected, and for some god forsaken reason I can't find out when a player exits, clientside.  This means that I can't use the looping functionality of the sound player because players who quit to the main menu will hear these sounds for the rest of their life.)
Fix crash when changing dimensions with multiple sounds playing.
Fix research error where VacuumTubes was being discovered, but not researched.  Will automatically discover all discoverable technologies on load from nbt, in the case that a new technology was thrown in since last start.
Fixed GuiTechnology title text.  Added several item textures.
Fixed dedicated/nondedicated server Femtocraft folder save locations.  Add advanced AI Core art.  Nano/Femto Coils.
Many textures.  Technology icon swaps/fixes.
Remove Thorium Rod.  More art.
Add missing .mcmeta files
