Code Issues Proposed changes

Add a simple whitespace linter

Browse Source 
The goimports tool does not check for trailing whitespaces in multiline
strings. This commit adds a simple linter to address this deficiency.

This change will also have the benefit of providing light linting of any
non-go files.
