2.It does not trigger RESET_DISABLE, and hence will not remove counters.
3.It does not check EFFECT_FLAG_CANNOT_DISABLE/EFFECT_CANNOT_DISEFFECT/EFFECT_CANNOT_DISABLE

It is used in c4694209

Now continuous effect in the phase will set core.conti_solving.
Continuous effects with EFFECT_FLAG_DELAY should be triggered after the operation is finished.

Duel.RemoveCounter(): It will raise field event EVENT_REMOVE_COUNTER.
Card.RemoveCounter(): The script should raise it manually.
Card,AddCounter(): It will raise single event EVENT_ADD_COUNTER.

This reverts commit 8a91d421.
