2014452802 -Added the ability to generate a file name based on formulas when sending a document

In the template, we added the setting for generating the name of the generated documents. With the configuration done, the files will be uploaded with the name that was formed due to the template. Implemented for actions: - issue a document (status); - write out a document based on the expected payments of the process and send it to the client by email (auto); - for the function of uploading documents to FTP; - to send a document from the order via the "Write email" button. When we indicate the need to add a document to the letter.
