Add a friendly message to comment form to update issue summary

I've got mixed feelings on this.

Pro: yes, we should try to encourage that behavior. ;)

Con: more help text just makes the issue UI overwhelming and less likely that people read *any* of the descriptions. The recurring theme of Bojhan and yoroy's feedback to most of my proposed d.o-UI changes is "use less help text". This goes against that generally valid position.

So, I'm kinda ambivalent about this for now, and I'd be happy to be convinced by a solid argument in either direction. ;)

Ooh, if we all had lots of time we could A/B test to see whether the text results in more issues summaries being create or not.

Another option is to change the "Edit" label to "Edit issue summary".

See also #1217286-60: Posting a comment changes too many issue node revision properties for some more UI thoughts on this whole mess. ;)

Ok, this still needs to be implemented. We can grab the update code from:

all/modules/project_issue/project_issue.module
template_preprocess_project_issue_issue_update_link()
$variables['update_link'] = t('<a class="issue-button" href="@update">Update this issue</a>', array('@update' => $update_url));

Which adds to all/modules/project_issue/theme/project-issue-issue-update-link.tpl.php

all/modules/drupalorg/drupalorg_project/drupalorg_project.module
drupalorg_project_preprocess_comment_wrapper()
$variables['comment_form_title'] = t('Add new comment') . ' | ' . l(t('Update this issue'), $update_link);

Which adds to all/themes/bluecheese/tpl/comment-wrapper.tpl.php

I just updated one of them in this patch.

I do think that we could do simple a/b testing with 1 million users by simply doing even/odd. If we just apply one approach to odd users and keep the other the same and see if there is an up-take of participation.

We really need to be making these changes based on analytics.

With everything in the same form, there is less of a barrier to updating the issue summary today.
