block-blog_recent MDL-22942 Fixed up block config function, blog_recent doesn't have global settings

Workshop aggregation is not expected to produce any output, just redirects back to the workshop main page

Thanks to mark williams for the report.

There was a problem with properties $to, $ReplyTo and $error_count that
are now private. $error_count is accessible via public IsError() method.
For the other two, we needed them just because of post-processing charset
conversion. So I just made sure that the charset is converted before
the recipent and reply-to names are added to the PHPMailer.

Also, I do not instantiate Typo3 during every email if it is not needed
and I pass the character set to it in lower case now as stated in
textlib documentation.

The method used to be set as private in PHPdocs @access property in the
versions for PHP4. But apparenty upstream considers the function public.
Also, if the function did not declare visibility explicitly, it was
considered public anyway.

PHP5 passes and returns reference to objects automatically, no need for
reference operator any more.

message MDL-24694 made the email message processor report success if the recipient has said they don't want to receive emails so that code sending messages isnt bothered by what looks like a failure.

message MDL-25033 made the contact paging elements clickable even if they spill over into the right hand pane

global search MDL-25009 indexing failures in each module are now handled so that indexing can proceed to the next module.

also a temp fix (MDL-24822) for forum groupid.

It was unnecessary on modern browsers, since they let thought a pop-up if you just clicked on a link, so this check was just causing an annoying and misleading alert.

Since the popupchecker was only used here, and since it was implemented in a way that does not work on all browsers, I just deleted the function. If anyone ever finds that they acutally need this functionality, they can re-implement it in a way that works.

The code was behaving as if it was always true.

The unerlying problem seemed to be too many uses of pass-by-reference in listlib, where it was not necessary.
In investigating this code, I ended up doing a fair bit of cleaning up. Apologies that it leads to an unclear changeset.

Unit tests MDL-24976 Fixed conditionlib unit test (also added thing to ensure that debug warning in conditionlib is shown in unit test if applicable)
