13825	Large files should not be previewed during upload.	Jakub Ś		"Add-on to #13824

1. Drop large file into editor e.g. 30MB image 
2. Try clicking in to editor
**Result:** Eeditor doesn't respond because it processes base64 string to display image in editor. **Also the very important thing to notice is that upload of such file with preview feature used takes much much longer.**

We should introduce configuration variable for maximum file size for which preview should be displayed. Any file above that size will be uploaded without the preview. Image will be displayed only after the file is fully uploaded to the server.
