Enhance extensibility of the siteconfig settings template.
Review Request #6581 — Created Nov. 12, 2014 and submitted — Latest diff uploaded
The siteconfig settings template has some new blocks that allow for better overriding of content, especially when used through the configure_extension.html template. The page title can now be changed without overriding the entire title tag. There's a block for the particular page's subtitle, separate from the page-wide title block. The buttons box at the bottom of the page can be replaced or augmented as well. The Save button can be replaced, and pages can add additional buttons wherever they wish.
Made use of all these in a template.
