FITMESH-6, FITMESH-20  Fix for some objects disappearing when hardware skinning enabled and ALM disabled.

Tried to add consistent mesh upload retries in the HTTP work but a
combination of bad status choices in the upload service and the

add application-level retry.

Shrink floater and add a "!" icon in the top left corner.
