Fixes #49
it does this by adding a 'save as' button in the content editor. After you save as a new file you have to press ctrl+R to reload the content editor and the new entry you created will show up in the list. I'd like to change it so pressing ctrl+R
This allows you to save exactly one entry to a seperate json file, which is useful for modinfo for example. If you want to create a seperate file with a bunch of armors, you would save an existing armor as a new file and then copy the entry a couple of times, they will then be in the same file.
