Phase 1 of repo reorg (#719)

* Remove unneeded script * Rename Substrate Demo -> Substrate * Rename demo -> node * Build wasm from last rename. * Merge ed25519 into substrate-primitives * Minor tweak * Rename substrate -> core * Move substrate-runtime-support to core/runtime/support * Rename/move substrate-runtime-version * Move codec up a level * Rename substrate-codec -> parity-codec * Move environmental up a level * Move pwasm-* up to top, ready for removal * Remove requirement of s-r-support from s-r-primitives * Move core/runtime/primitives into core/runtime-primitives * Remove s-r-support dep from s-r-version * Remove dep of s-r-support from bft * Remove dep of s-r-support from node/consensus * Sever all other core deps from s-r-support * Forgot the no_std directive * Rename non-SRML modules to sr-* to avoid match clashes * Move runtime/* to srml/* * Rename substrate-runtime-* -> srml-* * Move srml to top-level
