#360 request to allow op defender to ignore Min % Owned setting

[Baruk Khazad!]

Please see forum post http://www.mekwars.org/forum/viewtopic.php?f=5&t=8476

The attached 4 files are
common/campaign/operations/DefaultOperation.java
OperationsEditor/dialog/OperationsDialog.java
server/campaign/operations/OperationWriter.java
server/campaign/operations/ShortValidator.java

The changes were made based on all existing instances of the MinPlanetOwnership operations setting (where the ops setting MinPlanetOwnership shows up, MinPlanetOwnershipIgnoredByDefender was added) and all changes are marked by "//Baruk Khazad! - 20151003"

The change for server/campaign/operations/ShortValidator.java is a nested if statement within the original Fail-if statement that will allow the op validation to continue without failing if the conditions were met. The changes to the other files are so the new ops setting is handled as the existing are.
