Main algorithm of the program for interaction with user

Acceptance criteria:

• bot should follow algorith
  

[VitalyOrfenov]

1. I think it's better to send some more instructions after "start command received". User will know what to do
2. There is no tip of the arrow that's comming from "Authorize user" to DB
3. What does "Count of images without watch >1" means? You gotta name it properly, so other devs could understand what is going on there
4. Move "No" and "Yes" words after XOR-gate closer to corresponding connectors so viewer could understand which where to go in which scenario
5. Each gate should have only one input and several outputs or several inputs and only one output. Not several inputs and several outputs at the same time
6. "User end chat" is on wrong lane. After user sends "stop" command the app stops listening for user commands, so it is App event, not Users
7. Event "View image" is not named like it is event. You gotta name in like "Image received" or something like that
8. Rephrase "Request add sites list for image searching" and "Image searching on sites" processes
9. "User send "stop" command" should be process, not event
10. Choose the way you mark "XOR"-gates. It should be either "X" inside, or it should be empty
