Add Pony House into the client list

[JasminDreasond]

This is a project that initially started as a fork of Cinny. Now it is currently advancing on its own path.
I'm trying to develop the most personalized client possible with the best amount of features for all types of users (and everything being possible to turn on or off). Currently I'm trying to bring compatibility to mobile, but the web version and desktop version are already compatible.

The project also promises to be compatible with mods (which is still in alpha version)
But the basic features to function as a conversational chat are already available.
