Web Inspector: DataGrid refactoring: make cell editing more generic.
https://bugs.webkit.org/show_bug.cgi?id=105849

Patch by Eugene Klyuchnikov <eustas@chromium.org> on 2013-01-10
Reviewed by Pavel Feldman.

Source/WebCore:

Editing feature has been added to DataGrid to edit localStorage.
Column numbers (0 and 1) are hardcoded.

This patch makes column editing feature more generic: remove hardcoded
colums, take "editable" column property into account.

This patch is a prerequisite for cookie editing.
