Check that all configuration variables being used

Plan: 1. create a unix script to perform automatic check 2. export all configuration variable names into one file in one variable per line format 3. use that file as input for a unix command "find" command 4. this way "find" command will be called on all project files for each config variable separately and will output what's been found 5. there is surely a way to report only variables, that were not found at all Idea is to automate process maximally. Please inspect all modules. Following configuration variables need to be implemented: ========================================================= Category_ShowPick - show editor's pick categories above other categories when enabled SocketBlockingMode - set socket blocking mode for all curl requests Comm_City, Comm_Contacts_Additional, Comm_ZIP - show on all templates, where Comm_AddressLine1 configuration variable is used (e.g. orders_blocks.tpl in In-Commerce) What is need to be done too: ============================ 1. remember in order record (before user sends request to payment gateway; usually in ord:OnCompleteOrder event): currency (that was selected on front-end) totalamount of order in selected currency
