As the title says, this commit is a massive overhaul.
I've rewritten/restrucuted almost everything in the controller scripts.
Because of that, there's a considerable possibility that I've broken
something somewhere.
Notable changes:
Added temporary uploads.
Removed file name length changer from dashboard,
in favor of an equivalent in homepage config tab.
This allows non-registered users to also set file name length.
A bunch of other undocmented stuff.
I don't know, I'm too tired to remember them all.
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.
