Make it override friendly

When overriding existing property configuration, not listed characteristics is kept at it's current value, e.g. when overriding enumerable property, and not stating new value for enumerable, the property will stay enumerable.

Currently there's no way with d to maintain such defaults, we need to be explicit about all property characteristics, otherwise it'll be just set to false. That's a big downside

Possibly it could work that way:

• d(value) - no configuration, keep current behavior { configurable: true, writable: true, enumerable: false, value })
• d('c!w', value) - Pass only listed configuration properties, and if we want to negate setting, precede it with !. Therefore in this example it'll turn to { configurable: true, writable: false, value }
