Converts the tool chain to use babel, eslint, and webpack vs. the previous proprietary solutions.
Additionally begins enforcing additional linting concerns as well as updates the code to reflect these rules.
Fixes#855Fixes#993
Causes templates to throw when lookup fields are not defined within the context. Strict mode will throw when any field is omitted. assumeObjects mode maintains the existing behavior of outputting an empty response when fields are not defined but allows for performance/size optimizations by not doing safety checks for intermediate objects in the lookup chain.
Strict mode effectively disables the helperMissing and inverse handling for blockHelperMissing as templates will throw rather than call those features for missing data fields.
