Print a message when loading a .ghci file

It'd be nice to have a notice displayed when ghci loads a .ghci file, something like

rwbarton@morphism:~$ ghci-7.10.1
GHCi, version 7.10.1: http://www.haskell.org/ghc/  :? for help
Loaded GHCi configuration from /home/rwbarton/.ghci
Prelude>

I want this mostly so that we can tell whether people filing ghci bugs might have anything relevant in their .ghci files.
