#50, #41, #49: fix missing MoviesFormat specifiers

Add missing MoviesFormat specifiers %tT, %t.T, %t_T.
Additionally sort specifiers in specific way before replacement to prevent short.
specifiers from early matching and thus preventing longer ones from working.
Add test case for %t_T - movie title (original letter case).
