storage : add "self" parameter to a couple of methods

needed by lua to use the same C function for multiple storages
signal : add a signal before export is started

This signal has one parameter : a glist of the imgid to be exported
This is used by lua to have callbacks
signal : add a signal after processing but before the storage uses the new image

this is used by lua to be able to tweak the exported image before the storage moves it to its final place
imageio : allow to find the index from the format or storage
signal : new signal for when a new storage is added

needed for lua because storages can be added after the GUI is built
