Tabs for organisation

[SekoiaTree]

A nice thing would be having tabs to organize all the items, as searching gets kinda clunky sometimes...
An alternative is being able to tag items and search by tags (such as #slabs, #planks and such) that already exist in vanilla.

Not gonna expand much more unless someone wants me to, I think this can be implemented in some nice ways

you can already search with item tags with # prefix and item/mod id with @, you can also combine them (in 2.1) like @minecraft #logs acacia. i also use String#contains instead of String#startsWith so you don't need the namespace to search
