Alexander Udalov 8f0885ca03 Rename KClass.properties and extensionProperties: prepend 'member'
To better emphasize the fact that all returned properties require an instance
of the class they are declared in. Another issue was that
'Some::class.extensionProperties' was sometimes incorrectly perceived as
"get all extension properties available on the class Some"
