[pve-devel] [PATCH manager 1/1] ui: implement 'Tag View' for the resource tree

[Dominik Csapak <d.csapak@proxmox.com>]

and keep the functionality in ResourceTree as generic as possible.

We achieve this by having an 'itemMap' function that can split one item
from the store into multiple to add to the tree.

for the updates, we have to have an 'idMapFn' (to get the original id
back)

we also have to modify how the move checks work a bit, since we only
want to move the items when the tags changed only in the tagview case

in the ResourceGrid we have to get the id a bit differently since we now
have 'virtual' ids for the entries tag contain the tag (which can't be
found in the resource store)

this depends on the docs (onlineHelp ref) and widget toolkit (css)
patches

there is probably some optimization potential in how we handle the
overrides, but i tried to keep it as generic as possible so that
we can extend it easily if we want to.
