Excel Plug-In: Refresh all dataset connections at once

Dean_Wangerin

Currently with the Excel Plug-In there's no way to refresh all datasets at once. The normal use case it to refresh all the data, but right now it requires tediously going to each sheet, hitting refresh, then hitting Next and Finish on each sheet.  It should instead mirror Excel's pivot tables where there's a Refresh All button, and clicking it will refresh all the data, with no prompts, questions, or pop-ups.
