Removing translateString forces using data-i18n attributes, to make sure we do not forget to set them.

Missing data-i18n attributes is also problem that strings will not be translated when changing language.

Renames 'videoConnectionMessage' to 'localConnectionMessage', because
it is displayed when we're having problems with our local connection
and a different one will be shown for the remote connectivity issues.
Grey filter will be applied to the remote video/avatar displayed on
"large" and a message indicating remote connectivity issues will be
shown on top of that.
