Specifying data-objectParams-preloadermarkup crashed requests when editing.

[David-Polehonski]

Attempting to specify a value for objectParams.preloadermarkup crashes requests when using the layout manager as the markup is serialised into the URL and can easily exceed browser limits.

I've resolved the issue locally with a custom distribution of mura.js where I've modified the processAync request to use a post request instead.

if(typeof data.preloadermarkup != 'undefined'){
  self.innerHTML = data.preloadermarkup;
} else {
  self.innerHTML = Mura.preloaderMarkup;
}

ajax({
  url: Mura.apiEndpoint + '?method=processAsyncObject',
  type: 'post',
  data: data,
  success: function(resp) {
    handleResponse(obj,resp);
    if (typeof resolve =='function') {
      if(typeof resolve.call == 'undefined'){
    resolve(obj);
      } else { 
        resolve.call(obj.node, obj);
      }
    }
  }
});

I put in a partial fix. I'm still thinking about any potential issue moving from get to post perhaps related to browser caching or something.

Removing the markup from the request should resolve the issue but I could find no evidence to indicate whether this was required on the server-side or not.
