Added Stargate Cover Block system - Stargates can now be covered with ordinary Blocks (Blocks which don't have Block Entities tied to them)
Added config for how much power can Energy / Transfer Crystals in DHDs work with
Added getPointOfOrigin() and getSymbols() functions for Interfaces

Changed:

Interfaces are no longer valid redstone conductors
Powering the Basic Interface with redstone while it's in Shielding mode will now control the Iris if the Stargate has one (1-7 closes the iris | 8-15 opens the iris)
Stargate will now load the chunk it's in while it's connected to another Stargate (can be disabled in config)
Changed texture for Pegasus Stargate chevrons (the version that doesn't light up at the back) and Atlantis Stargate to be closer to the one seen in the show
Reworked Stargate Variants to be resourcepack-based
Stargate Variants can now specify the sound of every single chevron in every possible situation (incoming, engaged, encoded, open)
Stargate Variants can now specify the back texture of the Event Horizon separately
Stargate Variants can now specify the amount of distortion on the Event Horizon
Default Stargate models now exist as default Stargate Variants, allowing resourcepacks to change anything Stargate Variants could change (symbol color, when symbols are glowing, whether the Stargate should have a vortex)

Kawoosh should no longer be able to destroy Graves from the GraveStone mod
Fixed "Stargate does not have enugh space" random message appearing when Apotheosis is installed
Fixed Classic Stargate not generating a random Point of Origin when it's created from blocks
Fixed crash when dialing the 9th movie-style Stargate chevron when the encoded symbol isn't Point of Origin
