Add "On Hold" as a new status#190

Sometime, you don’t abandon a game, but rather jump into new hot game and you decide to come back to it later on. I differentiate play later and on hold game differently. Play later is something that I will play later but haven’t started, while “On Hold” is something I started but got distracted by some other games but will surely come back to finish it.

Sounds useful but isn’t that what “Play Next” is for? That’s more or less how I use it, anyway.
