Gadget export

To export the custom-js gadget, click on "Download" button, save the downloaded file, go to Special:Import on the destination wiki and upload it. Then add the following to MediaWiki:Gadgets-definition page:

* custom-js[ResourceLoader|default|hidden|type=general|skins=vector|dependencies=ext.gadget.rsw-util]|runerealm.js

You must have appropriate permissions on the destination wiki (including the right to edit system messages) and import from file uploads must be enabled.
