Change to Concentration type spells

[Polare]

As per owner vote, the following change should be added under the heading for "Concentration" spells:

The recipient of a Magic Storm, Earth/Chaos Storm, Fortress, Desecrate, or Sanctuary spell may choose (after appropriate defenses) to decline the spell simply by not applying the physical requirements (arms crossed, arms in the air, etc.). This does not apply to any other spells not listed above. In no cases can the spells listed above be used to force an unwilling target to break another spells' physical requirements (such as Repel requiring an arm to be held out).

The intent of this change is to make it so that Concentration spells which require certain physical requirements to complete cannot be used offensively to break another such spell. Note that this alters and reverses an earlier ARC ruling, the post on which will be updated to reflect this.
