* Switched standard to eslint with eslint-config-standard (and 4 more eslint plugins needed by standard). * Added "curly" eslint rule with "all" option. I like it. * Refactored all JS files to apply the new "curly" eslint rule. * Renewed axios.min.js, dropzone.min.js and sweetalert.min.js. Re-minified and added a small comment stating their version and copyright statement. * Some buttons in dashboard will now show loading icon whenever they're waiting for response from the server. * Updated README.md and .gitignore.
