Include complex TimeControl values additionally as value

[mliebelt]

TimeControls may be complex, but when writing them, it would be best to write them just as a value, to not repeat what the parser has already checked. So the writer would be able to just write the value all the time (as it already does for all other tags). no special handling would then be needed.

Should work on the one that is missing, but good enough to have a new release. Ensure that the missing tag is included then as fast as possible.
