modify hide_column_headers annotation

[RFSH]

This attribute is currently defined in the table-display annotation and can be used to hide the column headers on the record page. The changes that we should do regarding this attribute are:

• [x] Fix the documentation that is saying it's used in compact context (it's used in detailed).
• [ ] Rename it to hide_column_header to be consistent with the other annotations (namely show_nulls and show_foreign_key_link).
• [x] Allow it to be defined under column-display annotation as well. Then chaise should use this attribute to hide the specific column (instead of hiding all the columns). This will avoid the current custom-css changes that we're doing in rbk/gudmap to hide the column header for the treeview.

update:

• column display contextualized?
  • apply to just record app

Implementing these changes will fix issue #1993 in chaise.

PR #868 has been merged into master. In chaise, this is only implemented for the record app (detailed context).

@RFSH should we keep this issue open because of the 2nd bullet point?

[RFSH]

Yes, I think so. And it's a very small change (I don't think it's worth creating an extra issue for it)

[RFSH]

I renamed hide_column_headers to hide_column_header in this commit. I didn't remove the old name and it should still work for backwards compatibility purposes.
