Improvements and bugfixes refs #2242.
* Added tooltip to "play" button on pipeline templates page.
* Adjusted play button styling.
* Added a little bit of text to tell the user what to do on the parameter editing page.
* Moved "run pipeline" button to the tab bar row.
* Fixed the "-selection-" and "-recent-" dividers to be invalid selections.
* Tweaked editing popup label to say "set value for xxx" instead of "update xxx"
* Refactored status labels and progress bars for jobs and pipelines into partials that should be used everywhere consistently
* Fixed automatic refresh of pipeline instance page to emit ajax:complete event, and fixed shown.bs.tab event to catch all events and then apply the selector, instead of having to use the selector to attach events to specific DOM nodes (which breaks when the page is refreshed.)
