[WIP] Add support for object keys, labels

[MaximSokolov]

label:

switch (foo())
{
    case 'string':
    case a:
    case a + b:
    case foo(bar):
    case CON$TANT:
    case 123:
      foo(bar)
      break;
    default:
}

? a : b
? "abc" : "abc"
? (a.b(123)) : (b("c"))
? {key: value} : b
? this : null
? 'a'.b(':c(d)') :

obj = {
  key: value,
  $abc$: value,
  'key': 'value',
  KEY: VALUE
}

obj1 = {
  name: function (){},
  'name': function (){},
  "name": function(){}
}

obj2 = {
  null: 'abc',
  module: 'abc',
  this: 'abc',
  class: 'abc',
  NaN: 'abc'
}

atom-text-editor::shadow .source.js {
  .meta.object-key {
    // * {}

    .variable {}

    .constant.numeric {}

    .string {}

    .constant.other {}
  }

  .meta.function {
    .meta.object-key {
      .entity.name.function, .string {}
    }
  }
}

I mean, this does seem to clear up some of the regexes. The case/default stuff is definitely something that can be improved though, and may also allow us to match labels correctly. Can you try putting that in a separate repository (maybe 'include': '#switch-case'), and only call that when we hit a switch statement?

[MaximSokolov]

Objects literals inside ternary expression fixed by using begin/end matching for curly brackets. Looking for the following word in key pattern allows to match labels properly. The case/default moved to a switch_statement repo.

@MaximSokolov So is this ready for review, or are there more edge cases that need to be addressed?

[MaximSokolov]

It's ready for review. However PR brings highlighting changes, so I want to add before/after info and steps to change colors before merging

[winstliu]

Can't this be (\\basync\\b)? instead?

[winstliu]

Pretty useless switch 😆

[winstliu]

This will also need to be rebased.

I'd like to mention a special case, just to make sure it gets addressed with these changes when they're done: #334 (comment)
