Apply Selected as a Patch operation

[eonwarped]

Was in need of this feature and had a bit of a hack to accomplish what I needed. Sometimes I'd want to bulk adjust everyone selected and only adjust for example the timing to 15 minutes. If I wanted to do that now, I'd have to group the accounts by similar settings and handle it that way.

Suggestion: In the "apply selected" dialog, when specifying "empty" settings, have it preserve the existing setting in each row.

Here is what I did as a workaround to mass set everyone's daily limit to 1:

Select a bunch of people.
Set a breakpoint inside the settingsforselectedfans function, and advance to just before the for loop.
Then run the following in the console:

for(var i=0, n=checkboxes.length;i<n;i++) { 
  if(checkboxes[i].checked){
    var user = checkboxes[i].id;

    // preserve minute
    minute = parseInt(checkboxes[i].parentNode.parentNode.getElementsByTagName('td')[5].firstChild.nodeValue);

    // preserve weight
    weight = parseInt(checkboxes[i].parentNode.parentNode.getElementsByTagName('td')[4].firstChild.nodeValue);

    const body = 'fan=' + encodeURIComponent(user) +
        '&weight=' + encodeURIComponent(weight) +
	'&minute=' + encodeURIComponent(minute) +
	'&enable=' + encodeURIComponent(enable) +
	'&dailylimit=' + encodeURIComponent(dailylimit)

        callApi('api/v1/dashboard/fanbase/settings', body)	
  }
}

Obviously it won't necessarily look like this, probably much cleaner ways to identify the correct cell.
