Clean up the issue tracker. Close old issues without follow up.

As a general maintenance task, for this issue tracker to be manageable, we are closing old issues (for now, the ones that haven't got any follow up in more than 1 year).

Anyway if we close an issue and you are still there and want to reopen it, please consider:

- If it is a bug report, check it still happens with latest version of the module before reopening. And anyway if no one has decided to work on a patch to fix it, maybe it was not that important.
- If it is a feature request, and no one has wanted to work on it for a long time, reopen only if you have a patch for it. I'm sorry but this is not a wish list. Note also that versions prior to 7.x are in a maintenance status, which means only bug fixes are welcomed for them but there's very little interest in new features for these versions.
- If it is a support request and no-one has replied for a year, maybe no-one had the time for it, or maybe your question was not easy to understand or maybe the answer is in the handbook. Anyway it is very unlikely that you get a reply in one more year.

So really, feel free to reopen if you believe you still have a cause, but consider that adding new issues to the tracker takes time from other issues still open so it's up to you to decide whether you want to slow down that other ones.

Thanks for your understanding.
