- all unused/unnecessary files remove
- `status-lib` references updated due to cleaning on that side
- necessary submodules added (those removed from status lib)
When we started with refactor we had to somehow separate "new"
and "old" signals that's why most of signals had prefix "new-", now
since we don't collide any more with "old" signal names (since we
removed all old code) we are free to sort out that signals naming,
what this commit does.
