Fix EsLint warnings and add some files to .gitignore (#60)

* Silence git about my local IDE files

This was copy-pasted from Citras .gitignore file.

* Fix some typos

* Prevent coercion warning

* Fix the rest of EsLinter warnings

Fixes wrong spacing, missing semicolons, unecessary RegEx escapes, unecessary undefined init and unused variables.

* Replace var with const or let
