This change creates a lib/text directory and moves all files with text-related logic to it. It also lays the ground for separating text parsing and display logic. (That change will introduce even more files with text-related logic which will crowd lib/media directory). Issue #796. Change-Id: I65ac134020a0126ff02a8f2067beb73870232e65
