Audaspace: Various fixes

- Fixed uninitialized result used in DynamicMusic::seek().

  The comment to this function says false is returned if the handle
  is invalid, while in practice non-initialized value will be returned.

- Spelling typos in comment.

- Silence -Wdelete-non-abstract-non-virtual-dtor warning.
