Impliment full keyboard support
At the moment wave engine doesn't support all the keyboard buttons across cultures. For example, it doesn't support the majority of symbol keys on my en-uk keyboard and I imagine it is the same for other cultures. One example of where this impacts is typing an email address which is virtually impossible as '@' and '.' are not where they should be. Textbox can be extended to create culture compatibility, but without the key support in WaveEngine.Common.Input.KeyboardState it is impossible.
