Fixes#1284
Appearently, there is a use-case of stringifying the error in order to
evaluated its properties on another system. There was a regression
from 4.0.5 to 4.0.6 that the column-property of compilation errors
was not enumerable anymore in 4.0.6 (due to commit 20c965c) and
thus was not included in the output of "JSON.stringify".
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.
