Bug Fix - composeF4 -> parse -> composeF4

- Fixed bug that meant Task::composeF4 added a newline, but Task::parse
  did not expect a newline.  This caused Task::determineVersion to
  detect a format 1 encoding and throw.  Changed TDB::load to not remove
  any \n characters, and Task::parse to accept lines either with or
  without.
