make grid headers in Angular admin interfaces sticky

[Galen Charlton]

Grid headers in Angular admin interfaces should be "sticky" by default, as there are many where a user might want to scroll through a large number of rows to find a setting or policy to change.

Given the brevity of describing the change, I've elected to not supply a release notes entry.

I tested this with several different admin grids, including carousels, and standing penalty types. In all cases I'm seeing sticky grid headers.

I have tested this and consent to signing off on this with my name Mike Risher and my email <email address hidden>

Thanks, Galen and Mike. I pushed this to master and rel_3_6. I chose not to backport to 3.5.
