Add support for osu!lazer

[mellowagain]

With the first development build being available soon for osu!lazer on Android, pretty much all major platforms are supported by osu!lazer.

In response to this Shiro will add support for osu!lazer clients. This requires some major changes in the project, so this isn't of the highest priority at the moment.

Note: The clients detection feature in Shiro already supports osu!lazer.
