Web Inspector: console.table with columnName filter for non-existent property should still show column

[Joseph Pecoraro]

* SUMMARY
console.table with columnName filter for non-existent property should still show column.

* TEST
var p1 = { first: "Joe", last: "Peck", age: 10 };
var p2 = { first: "First", last: "Last", age: 20 };
console.table([p1, p2], ["first", "age", "middle"]);

* EXPECTED OUTPUT
Table with "(Index)", "first", "age", and "middle" columns.

* ACTUAL OUTPUT
Table with "(Index)", "first", and "age" columns. Since no object had a "middle" property.

* NOTES
- We should probably use the columnNames list as the proposed order of columns.
- We can improve the backend by not getting all property descriptors, and filtering on columnNames earlier / proactively

[PATCH] Proposed Fix

It kinda stinks that we pass this array to the frontend as a RemoteObject. This forces the frontend to peek into the preview to get string values. This could be an optional property on ConsoleMessage, but I felt it might make sense keeping it a "console.table" parameter like a "console.log" parameter. I can go with either approach.
