fix eosiod tests by swapping order of generic_currency's account fields to match balance serialization assumption in chain_plugin

There are a bunch of files that get installed (via something like make install) that make absolutely no sense. No one can do anything useful with the static library to the net_plugin, for example. Removing all of the obvious offenders. I left stuff that still doesn't feel appropriate to me like fc and appbase. Technically those can be used standalone outside of eosio. Save those for a separate PR one day since it could be more contentious.

bugfix in multi_index::update, generic_currency uses new api, tester::get_currency_balance fixed to support new row format

add parameter for tester construction to indicate whether it should push the genesis/funding transactions.  Setting this to false creates a testr that can be fed those transactions in a block.

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
