Web Inspector: Add ability to show/hide DataGird columns

[Matt Baker]

* SUMMARY
Add ability to show/hide DataGird columns. In OS X Finder, the grid header's context menu has checkbox items for each (eligible) column.

* NOTES
 - It should be possible to disallow showing/hiding certain columns (e.g., the "Name" column in timeline grids)
 - Hidden columns should be persisted in a setting

Same comment regarding FIXMEs with bugzilla links (seen below).

We should initialize this in the constructor to false, for clarity.

Hmm, is showColumn(id, false) really hiding the column? If so, we should rename this:

    setColumnVisible(columnIdentifier, visible)

That way its less of a mystery when "showColumn" gets called and its not shown.

Given that this method adds a bunch of things opportunistically to the context menu, we should probably avoid the early return style and nest everything in ifs, like you did with column.sortable above. That way when the next person adds something they won't need to indent everything.

I think a better way to do this is to just include the bug and a description if needed:

    // FIXME: <https://webkit.org/b/158675> Web Inspector: DataGrid should manage its own settings

That way I know what the bugzilla bug is without having to follow the link.
