First release

The first release is 0.24 because it starts from ufRaw v0.23
That's a BETA release tested only on my system.
Some feature are still uncomplete.
The backwards compatibility (with ufraw) should be assured.

• heavily reviewed the preview window (the main UI) in a more standard way
• global reset button
• new zone-view momentary rendering
• all panels are resizabile (paned boxes)
• standard gtk save window. The preview does not close when image is saved
• preview widget on the chooser dialog
• three cursor modes (drag, crop and spot) with buttons
  now cursor action depends on "cursor mode", not on netbook page
• separate the window configuration from the adjustment configuration (still uncomplete)
  windows configuration saves on .nufrawrc-ui everytime the window is closed
• all adjustment have expander, no more tabs/notebook
• histograms and curves can have any size
• reviewed and separated values table from live hostogram
• save configuration button moved in configuration tab of options window
• restyled settings tab in option window
• remember output path and overwrite moved to settings tab in options window
• display profile moved in settings tab of options window
• exif table columns are drag-resizable
• preset for grayscale color mixer (values are set according to typical color filters for b&w)
• basecurve and ICC profile moved together in "input" section
• monitor profile moved to option window
• file chooser hides during raw editing
• disabled "file delete" button (that's not the place)
• zoom slider
• blackpoint slider
• restyled crop/rotate section
• output size (shrink) and format are now in a new "output section"
