noise tools: get rid of aliasing properly
noise profile: canon eos 1d ii by cedric
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
storage : add a specific function to add a storage

that function will add it to the list and send the proper signal.
it will NOT initialise the storage structure.

This is needed by lua because lua will add storages after the initial
build of the storage list
colorlabels : use a table of names instead of a switch case.

lua can use the table directly to handle the enum
dt_control_export : pass the list of images to export instead of always using the selection
Do not add multi-name if empty.

Otherwise the name won't match the one in the module as some spaces are
added at the end.
Use blenop params when exporting with the style.

This is probably a left over of the initial implementation I did. I see
no reason to not use the blenop params here.
