Now the plugin will update the bib citation key in the relevant page's alias property if Zotero has changed the key.
- The mechanism behind is to check if the citation key needs to be updated each time the plugin cites that paper from Zotero.
- Old alias keys will still be kept as alias of the page.
- In more complicated cases, like when the key clashes with existent pages in the graph, this plugin can do nothing yet. But this is almost unlikely to happen and even if it happens, there won't be any catastrophic outcome (just the bibtex key won't work as an alias).
