Fixes #34 - Remove "Choices" and "Base/Increment" from Category * Remove Choices and Base/Increment from code Re #47: Remove magic numbers * Replace "-1" magic number with WarFoundryCore.INFINITY * Use INFINITY instead of -1 in code * Use INF in schemas instead of -1 * Handle and parse INF as a special value in XML Factory
