Store the state for different input contexts

Fcitx allows different input context to held a different state. The state usually refers to the partially typed text and all other associated data structures. In Quwei case, the state is the digits that user already typed. To represent this, Fcitx provides a convenient class InputBuffer to allow engine to use this class conveniently to edit the internal state. In order to automatically construct the state when an input context getting constructed, Fcitx provides a framework called InputContextProperty. In order to use this, you first need to register a factory class to InputContextManager, via registerProperty. Each property need to have a global unique name. The name can be something human-understandable. In Quwei case, I just use "quweiState". The benefit of using a nicer name is just in case you're developing something cross addon (Another addon need to access certain internal state of this addon), you can use this common name to load it in a different addon. If you do not need access from outside, the name does not really matter.
