dolphin: convert panels/ and filterbar to qt signal/slot syntax

TerminalPanel connections to konsole part were not converted since there
is no header available that defines these function, we have to keep the
old syntax here.

Additionally the new syntax no longer accepts QPointer arguments, we have
to explicitly call .data() there.
