Doc: A simplified style for rendering docs with QTextBrowser

Add a new documentation template, with simplified CSS rules that
work better when using QTextBrowser as a backend for Qt Assistant
or Qt Creator Help.

Select this new template by default for offline documentation
builds, but keep the old offline template as part of the template
files; use JavaScript to switch to the 'standard' CSS when the
generated files are viewed with a web browser.
