Partly fix state_db getCode for 20 new working GeneralStateTests ( #156 )
...
* partly fix state_db getCode to get 20 new working GeneralStateTests; remove 2 functions which existed as workarounds; switch all remaining setBalance calls in GeneralStateTestRunner to subBalance (addBalance calls already changed)
* two of the 20 new tests don't work in 32-bit builds

* fix 32-bit issue in AppVeyor
* allow another dozen or so GeneralStateTest fixtures which work on 64-bit, but not on 32-bit platforms, to safely-fail, but demarcate them separately to facilitate debugging
* steal fa672600eb

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
