Improve log entries display in change lists

Log entries are wrapped with parenthesis - not hardcoded into HTML
causing stray brackets in Minerva where this element is floated.
Has no impact on other skins

In addition to this the entire log entry item is wrapped in a new
span mw-changeslist-log-entry to ensure the text is recognised
as a whole entity - on Minerva floats were leading to the action
and the action object being separated (e.g. uploaded and "File:Name
were separated
