changes recording datatype from BLOB to VARCHAR, as I made up my mind and think, that storing the recordings as files somewhere is better than putting them in the database. recording should point to the path where the file can be found. (Maybe is copied and renamed to a nice place within the userspace)

 - Show movements through works (`sw work_number`)
 - Mark movement as mastered for active user (`m number_of_work number_of_movement`)
 - Show possible commands (`h`)
-- (planned) Show mastered works/movements for activated user
+- Show mastered movements for activated user (`sm`)
+- (planned) display, if work or movement is mastered from active user when viewing works and movements
 - (planned) Save recordings per movement in db
 - (planned) Listen to saved recordings
+- (planned) Works are shown sorted (opus, collection e.g. "Walzer", "Sonaten")
