Erply API version 1.6.5

Physical stocktaking counts can be annotated with comments: field "comment" added to API getStocktakingReadings and saveStocktakingReadings.
Support for promotions requiring manager's approval has been added.
- Flag "requiresManagerOverride" added to API getCampaigns and saveCampaign.
- Flag "rightPOSManagerOverride" added to API getUserRights.
- If a manual promotion is marked with the abovementioned flag (requires store manager's approval) then POS should prompt for a store manager's PIN or password. (A store manager is anyone with the "rightPOSManagerOverride" flag.)
Fixed: API calculateShoppingCart now supports applying a promotion manually multiple times.

Field "euInvoiceType" added to API calculateShoppingCart.
Support for product extra codes (Code 5 - Code 8) added to API saveMasterListProducts and API copyMasterListProductsToErply.
