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.
Moved page.prepareShareX() to a single JS file named sharex.js. It'll be loaded in home and dashboard pages, and both home.js and dashboard.js will rely on the function provided by it.
The generated ShareX config file will also properly support cases where the safe is being hosted in a subdir now (e.i. https://example.com/lolisafe).
