Subject: [PATCH] GUI: Suggest using project file if one is found.

If we there is project file in the directory to check then ask
user if one wants to use the project file instead. If there are
multiple project files then just tell there are project files
and ask if user wants to continue without using them.

Ticket: #2816 (GUI regression: Interrupted checking because of too many #ifdef configurations.)
