This Pull Request resolve #19 (allow different price for different mode of shipping) Also close #16 (traduction)

Update price storage

• Change price storage form json file to BDD table
• Add different tab in admin for allow to choose different price and different freeshipping for different mode of socolissimo
• Add new field freeshipping_from to allow to offer shipping if cart amount reach this montant

Update module for new feature different price per mode

• Update front for display good price for each mode and disable the only the specific mode if no price available
• Update module postage calcul for take the price of the selected mode

Update socolissimo admin

• Replace modals for each price by one modal because when we have ~80 price for each mode it take too long times for create all the modal with all the form insides instead we create one modal one time and after fill the field with the value of the price we need to change
• Add json import on activation One json called prices.json can be set for all mode price Or on file for each called prices_{mode-code}.json

I think this PR deserve its own release. You should change the version number in module.xml :)
