Apply code indentation

[nujabes403]

Some code's indentation is not aligned.

I applied code indentation according to some convention like below:

1. Add a space between comma and element item.
   (0,5) -> (0, 5)

2. Add a space between curly bracket and parenthesis.
   if (this.host.substring(0,5) === "https"){
   ->
   if (this.host.substring(0, 5) === "https") {

3. Add a space between reserved keyword and curly bracket.
   }else{
   ->
   } else {

Sometimes it is hard to follow the code convention rules, since there are so many different code convention. however, there is a 'anti-pattern' which harms readability to make hard finding bugs. I just fixed some 'anti-pattern' in this file. :)

@nujabes403 I'll close this PR because I already fixed the code style here #2000
