Ramp Time in Side Bar

I'd like ramp time to be included whenever the calculation mode combines hit dps with poison/impale dps. It's important context for the final dps number that players can miss when talking about X bajillion viper strike dps.

If the box is getting too crowded then maybe replace the "total damage per poison" stat, which doesn't seem very relevant when dps is concerned.

ramp time for poison dps = poison duration
ramp time for impale dps = max number of impales / attacks per second

ファイルやテストは指定されていません。まず、サイドバーの計算モード表示と、既存の poison、impale、total-damage-per-poison の各ステータスを見つけ、要求されている ramp time の式を現在の計算と比較します。結合した hit と poison/impale の DPS モードで、サイドバーを過密にせず ramp time が表示されれば完了です。
