Change indentation rules in json.kak to be much more intuitive for nested objects
Change indentation rules in json.kak to be much more intuitive for nested objects

As it was before, when you had this (| = cursor):

``` json
{
  "foo": {|
}
```

and hit <ret>, this would happen:

``` json
{
  "foo": {
  |
}
```

when it should have been this:
``` json
{
  "foo": {
    |
}
```
