[For Modders] ThingComp should have CompTickLong

[XeoNovaDan]

Although the Plant class is derived from ThingWithComps, one can't really add functional comps to plants since ThingComp only supports Tick and TickRare, yet plants use TickLong. I don't know if there are any other cases, and this suggestion is admittedly a niche one, but it'd be nice to have the ThingComp class have support for TickLong so that extra effects can be added to plants without having to make a new class which derives from the Plant class which could harm compatibility with other mods.
