renamed: WinixModel -> WinixModelDeprecated (this class will be removed)

added: WinixModel (models/winixmodel.h|cpp) - a class inheriting from morm::WinixModel, we have methods such as: get_config(), get_logger(), get_request()
       and this class will be a base class for our models
added: WinixModelConnector (models/winixmodelconnector.h|cpp) - a class inheriting from morm::WinixModelConnector
       this connector we are using instead of morm::ModelConnector - there are pointers to winix objects there (config, request, log)
added to Request: Ezc::Models models
removed from TemplatesFunctions: Ezc::Models ezc_models;
changed: ImgCrop winix functions is using its own item_tab vector now (not finished yet)
added: Item::is(), Item::link(), ItemContent::print_content()
