Userland: Rename IPC ClientConnection => ConnectionFromClient

This was done with CLion's automatic rename feature and with:
find . -name ClientConnection.h
    | rename 's/ClientConnection\.h/ConnectionFromClient.h/'

find . -name ClientConnection.cpp
    | rename 's/ClientConnection\.cpp/ConnectionFromClient.cpp/'
