Import crusaders from json string

This feature allows you to import into the fansite the data from the game that you can find in json raw format. The feature import, regarding crusaders, ownership, EP, Gears, Crafting recipes. For crusaders it works only in addition and substitution mode. This means that if, for example, for testing purposes, you have added a crusader you don't really own, the import feature won't remove it. But if you've put 500 EP on a crusader that you have with only 20 EP, the value will be reset to 20 EP. It imports also idols, talents, trinkets, objective completion, campaing formation and max area reached. In this case it works for total substitution of your values.
