[MD settings] merge polymer 1.0.11; hack for settings checkbox

This is a bower update of Polymer with the current
bower.json settings.  I'd like to change the bower.json
settings to bring in more polymer elements.  As a
precursor to that, this CL brings the current Polymer
elements up to date (without adding more elements).

While doing some brief testing, I found that the
paper-checkbox had changed in a way the broke the
settings-checkbox.  It looks like the settings-checkbox
should be updated/changed to cope, but that is beyond
the scope of this CL.  This CL includes a small hack
to fix the settings checkbox along with comments/notes
about the hack and what to do to remove the hack.

File chrome/browser/resources/settings/checkbox/checkbox.js (right):

https://codereview.chromium.org/1287713002/diff/1/chrome/browser/resources/se...
chrome/browser/resources/settings/checkbox/checkbox.js:67: },
Is there any reason why this was done here instead of in cr_checkbox.js? That is
broken also.
