* Modified Single Entry template (`/templates/entries/diy.php`) to be consistent Multiple Entries output. Before, the wrapper would output: `<div id="gv_diy_95" class="gv-diy-view">` for View #95, Entry #14257. Now, the wrapper outputs: `<div id="gv_diy_95" class="gv-diy-view gv-container gv-container-14257">`
* Added `gv-diy-container gv-diy-single-container` CSS classes to the wrapper `<div>`
* CSS classes are now passed through the `gv_container_class()` function
* `gravityview_header()` is now called before `$template::entry_before()` (needed for Inline Edit)
* Fixed: Inline Edit not running in the Single Entry context
