LinksMessageView component will receive the urls from nim as string and it will only forward the string to getLinkPreviewData slot implemented in nim together with some settings (supported img extensions and unfurling preferences)
On nim side the urls will be parsed and validated using the settings received from qml.
Images are now validated before sending them to the UI using the HEAD request.
Moved Message component & dependencies to shared
for usage import shared.views.chat 1.0 and accordingly
import shared.controls/panels.chat 1.0
