Silence shellcheck warnings (#255)

Browse Source 
* Made more specific shellcheck disables
* Fixed variable quoting (SC2086,SC2064)
* Use `$*` expansion instead of `$@` when not using arrays (SC2124)
* Use cleaner `$()` syntax instead of back quotes (SC2006)
* Improved comparator (SC2166)
* Minor improvements in coding style

Tested clean output using: `find -name "*.sh" | xargs -n1 shellcheck -x`.
