* support for loading cache for pseudo devices

* check for hrSystemUptime as well as sysUpTime for snmp connect

* display pseudo devices with yellow pill for name

* color all cells for layers for pseudo

* no need to b64 encode binary data in scalars as we b64 whole thing after

* working search

* minor ui fixes

* implement typeahead for leaf search

* limit rows in typeahead
