more VM tracing
...
The existing vmState tracing is plugged into chronicles, at the TRACE
level, to facilitate state test debugging.
Some useful chronicles defines are added to "tests/nim.cfg" to simplify
the compile-and-run command for individual tests.

general-state testsuite changes and better fork selection
...
- skipped the tests in allowedFailInCurrentBuild()
- replaced doAssert() with check() in testFixtureIndexes() so we can see
both hash values on failure
- checking filename extension for JSON tests to avoid editor swap files
- replaced the duplicated block values in the main net's ChainConfig
with values from forkBlocks
- allowed overriding the current fork in computations, because the old
strategy of only looking at the block number doesn't work with JSON tests
where the block number is usually 1
- explicitly pass the fork to gasCosts() and use it for conditional cost
calculation
- fixed a logic error in the CREATE opcode
- fixed VM selection based on current fork in updateOpcodeExec()
- single point of control for supported forks in tests (just one fork, at the
moment)
- 44 new test failures (that were probably passing for the wrong reasons)

replace logging module with nim-chronicles ( fixes #38 )
...
This blindly changes logging to nim-chronicles - issues that ensue:
* keeps gas cost computation logs hidden behind flag
* unclear if logScope is practical - for example, since vm is split over
many files, topics get lost when using simple top-level per-module
topics
* when passing named object around, scope should incliude the name of
the object but this is caught neither by logScope nor by dynamicLogScope
