Add <leader>i shortcut for :ImportJSImportAll
Add <leader>i shortcut for :ImportJSImportAll

Now that I pushed the commit that dedupes modules (26a66cb) and fixed
the ImportJSImportAll command (previous commit), importing multiple
variables at once is more useful again. This commit adds a <leader>i
shortcut to quickly run :ImportJSImportAll.
