dependence util version is strict

[AMDvsTMD]

why util version 0.10.3 is strict not with caret

[jfirebaugh]

This is preventing use in the browser, because util@0.10.3 depends on inherits@2.0.1, which does not include isaacs/inherits@8a07051.

This should be resolved by #44 and thus v2.0.0.

[ratoi-crysty]

Even though this is closed in 2.0.0, the problem still persists for 1.5.x versions. Therefore we should also apply this for 1.5.x version as well, as webpack@4.x depends on it via node-libs-browser, which currently causes some issues.
