Jehan b6856af9d8 app: GimpGradient now uses GeglColor. 
I still see some limitations in GimpGradient, and in particular, they are still
always stored as RGB in GGR files. It would be nice if we could store the actual
color format. This way, if someone chooses a gradient stop as Lab or CMYK color,
that's what the gradient file would keep track of. But also even storing the
space of a color (instead of storing/loading always in sRGB, even though this
may still work fine as we store unbounded double values). This might warrant for
a v2 of GGR file format.

This commit also fixes loading of SVG gradient which was apparently broken
regarding hexadecimal color parsing.

Finally I improve gegl_color_set_alpha() by adding an alpha channel when the
initial format had none.
