Issue #1322092: Undefined index warning in "Available Updates List" with hidden=TRUE base themes.  Making core visible until #986888 is resolved.

Issue #1202354 submitted by @coltrane: when fetching list of blocks, adds conditional when context is enabled to also check if there's a configured reaction to display blocks

Issue #1097482: override for views-view.tpl.php was based on an older version of the file, and threw a notice due to missing $admin_links variable.  This template is no longer needed in D7 now that content is a region instead of a variable.  Its original intension was to add a gutter.

Issue #1153598: renaming of ".block .inner" to ".gutter" broke grid overlay.  fixed by updating class names referenced by grid.

Issue #1151894: Moved comment padding from fusion_core to fusion_starter css.  Altered comment css targeting to fit D7.

- add gutter to page title

- node_top and node_bottom are now special case regions: their blocks do not receive gutters, and the wrapping divs for the region do not have a grid assignment.  these changes were required with the introduction of #block-system-main into d7.
- removed .inner wrapping div from node template.  that gutter is covered by #block-system-main .inner
- Issue #1002072: restored #content-group and #content-region wrappers.  these were removed along with #content-inner and #content-content, which seemed to fix the issue, but caused new problems with fluid layouts and flexible sidebar layouts.
