Backup project to include the _uploadfiles folder

[henjoe]

When backing up a project this will give you a .json file that contains all configuration of the server which is typically fine.
But I got this scenario where I tried to backup a fuxa project and my views include some images from external (which is in _uploadfiles folder), so when I uninstall the fuxa and upgrade it to newer version, I need to copy this folder and put it to the upgraded fuxa, and then load the backup project, that's what I do for a moment.

What I am suggesting is, it will be better that when backing up the project it also include those files in the _uploadfiles, so any images are also backup, most of scada I've seen is they are saving the project in like "zip" format and containing all related files there, I am thinking the same with fuxa, we can save it a zip file containing the:

1. json file for the server config
2. _uploadFiles folder for the images uploaded or any.

Then when loading a project, simply read the json file from the zip, and then copy the _uploadFiles folder to replace the existing _uploadFiles.
