Set patternShown only when it is actually shown

Open the stop in the Line screen if showing from a stop (solves T1393)

Fix STAR lines indicated differently in the MaTO Data

Use a different layout manager for the favorites, show ST1 instead of STAR 1 as the name

Filter lines also by description and not only name

Use button to look for the bus instead of selecting the pattern when open

Move code to try to understand how to switch from bus to vehicle and viceversa
