UI - Bug Fixes #1 & Restoring Server Side Filtering (Processes)

[wcgunter]

This PR solves the following issues/bugs:

• Deployments: Changed dropdown button to regular button for downloading list of deployments
• Processes: Moved the download button into the dropdown menu of "Actions"
• Processes: Fixed the automatic filtering of processes based on URL (which gets set when user clicks from Deployment page graphs)
• All pages: "Copied" tooltip now goes away after button has been clicked / mouse moves away
• History: Input variables table has been moved into the overview table. Implemented the details & summary strategy to prevent overwhelming the user.
• All pages: The arrow next to "Show All" (part of the details & summary) now correctly rotates when details are expanded.
• History: Table is now automatically sorted so that oldest items show first
• History & Processes: Removed input variable "WorkerId" as it is always null (with a type of null)
• Processes: Made the input variables' column minimum width larger so it is easier to read variable information
• Processes: Allow columns in the table to be hidden using the new "Column Visibility" button. By default, the StartedOnWorker, Superprocess ID, and UUID are hidden from view.

• Processes: Fixed open selected in new tab and copy all selected history pages.
• Processes: Fixed issue that caused improper server-side filtering of subprocesses (when searching for subprocesses of a superprocess, processes which had not yet been claimed by a worker / started would also appear).
• Processes: Updated how the DataTable fetches and loads data. Now uses ajax calls to directly communicate with the API to get process information and uses DT's "render" option to add interactive elements. This allows for faster loading (no longer have to fetch, load into dom, and then load into DT) and parallel calls to the API to gather information (long wait times have been reduced).
• Processes: Updated UI to include a pre-fetch filter on the top of the page. This filter reads & sets URL params. This allows the client to only fetch processes which are needed by the end user which allows for an exponential speedup of loading, especially with extremely large data sets.

• Processes: Added text which tells the user how many processes match the current filters they have set. Updates automatically as users interact with the filters.
