No more enforced curly for if/else/for/while/do blocks w/ one statement.
With that said, auto-fixed all JS files to follow the rule.
I'd also like to apologize for the inconveniences this commit cause,
after all it was me who intentionally enforced curly rule back then.
Why the change of heart?
After doing some more non-JS codes recently, I realized it was
pretty stupid of me to enforce that.
I can't remember why I extended the config with "eslint:recommended" instead of "standard" back then. I know I wanted to force an older ecmaversion, but even then it would still work just fine with standard.
I've fixed it now to use standard. I've also applied auto-fix to dashboard.js and home.js, which fixed some stray or missing whitespaces, as well as the indenting of case's inside switch statement.
* Downgraded ecma version of client-side scripts to v5. This change means no more backtick strings and some others.
* Massively modified auth.js, dashboard.js and home.js to support the downgrade (dashboard.js had the most changes).
* Removed enter key event handler from auth page. The previous code had some small issues. I'd rather not have the handler than let the issues persist. I'll eventually look into adding this again in the future.
* Updated uploadController.js to handle some invalid requests into /api/delete and /api/bulkdelete.
This commit is intended to downgrade codes in JS files used for browser to increase browsers compatibility.
This branch is still experimental and may require much more testing.
