libdeng2: Cleaner text representation of Records

Records are converted to text in a way that retains the structure of
the record more clearly: both subrecords and referenced records are
printed as an indented block.

Furthermore, a subrecord uses '.' as the separator in the output while
referenced records (and other values) use ':'.
