* revise /customnode/installed

improved: don't fetch data from cnr for the api
improved: change format {<cnr id>: <version>} -> {<module>: [<version>, <cnr id>]}

* fix condition

* improved: add `mode=imported` for startup snapshot

`/customnode/installed` - current snapshot
`/customnode/installed?mode=imported` - startup snapshot

* improved: move cache dir to user directory

* modified: /customnodes/installed
- show whole nodes including disabled
- format changed `key -> list` to `key -> dict`
