Update process list columns

Closes #1272 (closed)

This is quite complicated because most people do not have 32:9 screens to display 20 columns at once on this list. The original request makes no mention of dates at all, which definitely does not help.

I first swapped the ID and name columns as requested, then added by <creator> on the existing date column. This is how it looks like on a 1920×1080 screen:

Version 1

The table is already getting a little cramped, so I tried to shorten the Status column. The status column displays (not configured) when a process has not yet started, but when a process has not yet started, it is always unscheduled anyway. So I shortened the Unscheduled (not configured) to Unconfigured:

Version 2

This is a little nicer, but the Date column is still called Date. As I mentioned in this comment, the date column currently displays the finished date if it is set, or the started date (when the process has started but is not finished), or the creation date (if the process has not started at all). Renaming the column to Created does not make sense, unless we remove the start and finish dates which had been requested earlier. During a quick conversation, Bastien had suggested using three columns, like so:

Version 3

This is the version currently in this merge request, and it is quite cramped. It is of course worse on smaller screens, like 1600×900 which can be found on smol laptops.

So we have a lot of options to choose from:

• Use three columns
• Leave the date column untouched
• Use three lines on the date column to display each date
• Copy GitLab: Like with issues and merge requests, abandon the table display and use two or three lines per process
• Leave the date column as it is, but add a dropdown to display each date in detail when hovered
• Leave the date column as it is, but display all the dates and the process creator in the process details page instead
• Some secret plan I didn't think of
