fixes for the build post-merge from master, though some of these fixes were probably needed pre-merge

removed unit tests for deprecated native contract actions

moved EOS transfers in the unit tests over to ABI serializer assisted methods (also in the tester library)

Removed stake from the newaccount tests and the corresponding abi tests

removed the benchmark command and several other now deprecated commands from eosioc

Updated the ABI, fixed implementation of `get_currency_balance` in the tester, separated out currency tests, added verification that balances are what is expected

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

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

save and restore pending transactions when pushing blocks, add transfer helper to tester, and adding get helper
