Lack of warning when JavaScript is disabled

[Kyrylo Romanenko]

Steps to reproduce:

1) Disable JavaScript in browser settings.
2) Navigate to Horizon.
3) Login to Horizon Dashboard.

Actual: Horizon Dashboard looks usually, but performs malfunction of most Horizon capabilities.

Expected: to see some warning to enable JavaScript.

Agreed that it would be better to detect when javascript is disabled and put up a warning than to present a UI that only works partially.
