* Add minimum and maximum target counts as parameters for TargetAmount and its subclasses; update/add several rules comments (and one actual text) for clarity; remove unused imports
* Get amount+description from target instead of parameters for DistributeCountersEffect and DamageMultiEffect; additions to TargetImpl.getDescription to accommodate
* Create separate method to check if "any number" phrasing should be used, override it in TargetAmount
* Check instanceof TargetAmount before casting
* Add new constructors to chain off of for TargetCreaturePermanentAmount & TargetCreatureOrPlaneswalkerAmount
* Fix text for Storm the Seedcore
* Use Integer.MAX_VALUE instead of 0 to represent no maximum targets
* Add comment about getUseAnyNumber()
* Use amount-only constructors in some TargetAmount subclasses, add clarifying documentation
* Fix a few calls
* Require more specific filters
* [SLD] Implement Captain America, First Avenger
I made assumptions that WotC is going to fix the rules by adding "choose the equipment you're unattaching with Throw..." to rule 601.2b so that this card actually functions since you have to choose a TargetAnyTargetAmount in steps 601.2c/601.2d long before you actually pay the unattach cost in 601.2h.
* Remove Target workaround, add proper 601.2b handling for choosing cost targets early using inheritance to avoid having a horrific brittle list of 'these costs must be paid early'.
* apply regex to change public copy constructors to protected
* cleanup code using now protected constructors
* fix manaBuilder weird casting of Mana into ConditionalMana
