Experiment with Telegram API

[ivysochyn]

The task is to get in touch with Telegram API in order to send offers to users.

Subtasks:

• Add a command to add a search term.
• Add a command to list all the search terms.
• Store search terms in a separate database with the primary key as a user id.

I have added the initial state of the 'search' generation functionality.

What was added:

• The ability for the user to list all his searches.
• The ability for users to add new searches with a given range for three following cities:
  • Poznań
  • Gdańsk
  • Warszawa

What left to do:

• Search should be reworked from the plain text, into a clickable button
• User should be able to delete a search
• Enhance search with optional parameters (area, floor, etc..)
• User should be able to list all the search parameters

The current version of the code requires refactoring.

I have increased the number of cities to search in.

Enhanced the search listing and started working on a function to manage the search queries.

Merged changes. All further enhancements to the search system should be done in a separate task.
