Direct access to the MCreator element .jsons

Quite a few of MCreator's limitations can be resolved by directly editing the workspace element .mod.json files, but this is inconvenient for a few reasons:

1. There's no shortcut to view or edit the element files from within MCreator.
2. Although you could alternatively edit the .java code generated from the element .mod.jsons, any changes you make are lost unless you lock the element.
3. Changes that are made to the element .mod.jsons externally via text editor are not updated live; you have to close and reopen MCreator to actually view and save any edits.

I think that the addition of a way to view and edit the element .mod.json files directly from within MCreator using the builtin code editor would be a very useful feature to consider implementing.
