nit: closeDialog

Here I am using a function which is defined in
chrome/browser/ui/webui/constrained_web_dialog_ui.cc. Changing the definition
there would require some changes to other files, too. Should I do this?
I could also define my own function, but I thought reusing an existing function
if possible would be better.

Personally I would rename it, but feel free to do in a followup CL or add a
TODO.

[Adrian Kuegel, 2013/02/14 10:36:12]

Ok, then I will add a TODO and do it in a later CL, because it will take some
time for me to make sure I don't miss a place where this is used. Unfortunately,
'DialogClose' is also used in other places referring to another function, so I
can't just replace all instances in the code (unless I change the definition of
the other function as well).
