Double increment on successful challenge

[ddugovic]

increment works provided you also get increment on a successful challenge and you totally should since challenging removes your premove from the board https://discord.com/channels/741321677828522035/768500754654429275/845003196547465236

On Lichess and Lishogi I recommend increment & byo-yomi respectively, however with OMGWords there is the possibility of an opponent trolling to remove your premove from the board.
