Quick Bar should only capitalize letters in Command Palette

[donkawechico]

Proposed change

Entity IDs (and friendly names) are currently being title-cased which isn't appropriate. We should only do sentence-casing for Command Palette items (to fix the issue of inconsistent string capitalizing rules in en.json)
