Add command & args to container source column

[adamint]

Show container command and args in the source column on resources tab if they have been set. As args will be more common than command, command is prefixed with Command: {command}.

Fixes #1122

Instead of making the value of the column longer/wider, what do you think about making it multi-row, like the executables view is (where the executable path and args are on one line and working directory is on a second line)? That'd also avoid the switching from regular text to subtext back to regular text on the same line (not sure that's an issue, but it feels off at first glance).

Good idea. Done
