Allow bypass “patch” save with ALT+Save

This just makes it possible to work around the issue in the FB case. The workaround is to hold the ALT key while saving to force a full save rather than a patch. The patch library causes the browser to crash with some forms.
Yes, it's handy to have a record of saves in the console. I've wished for this in the past. Note that this only affects the stand-alone version.
