refactor: remove cell::RefCell, rename TIMERS_QUEUE variable, and etc. (check desc)
Removed unused import, renamed static variable (TIMERS_QUEUE -> TASKS_QUEUE) and refactored get_instance() and show_infobar() methods. Return value has been changed (Self -> &'static Self) in get_instance() method. A check for opening an infobar has been added and renamed used static variables in show_infobar() method.
