- enforce that only priv accounts can contain "eosio."
- fix test that had name longer than 12 chars

Refactors much of the multi-wasm-runtime code to remove duplication and global accessors. WAVM is currently non functional because of some problems with passing through the non-global apply_context

the removal of `init` from `setcode` moved compilation AND validation of wasm to the first action.  We should do validation during `setcode` but doing this properly requires additional work.  This is a temporary fix

Additionally, the injector code was failing when hit with hand crafted wasm that had no types/import section(s)

- added api to update producers from wasm
- removed staked_balance objects and other deprecated code

rename scopes to locks from the perspective of the contracts, add account to the locks in shards and then deal with all the problems that caused

removed scope from transaction
renamed scope on action to account
added scopes to shard
fixed up scheduling and tests
fixed up eosioc

STAT-306 #970 Replay causes assertion

(reapplied on noon branch)

fixed bugs in error handling WRT database undo states, fixed bugs in contract-side parsing of deferred transactions, added published time and sender (if one exists) to the apply_context and wasm ABI

added tests for the WASM currency contract and fixed issues it exposed, refactored contract initialization as a require_recipient where the logic of init vs apply is now in the wasm_interface

restored db table objects, extracted scope,code,table triplet from tables into a table id, moved EOSIO tokens to use the same data model as wasm token contracts

Added test for basic wasm contract loading/unloading.  Fixed bugs in the intrinsic code and made it impossible to complile with the same class of bugs in the future.  Did some basic style/renaming in the contracts directory and in the enclosed tutorial/doxygen files
