hex Colors in Geojsons and colormaps

[qchasserieau]

• If there is a color field in a geojson with hex codes : make it possible to use as is by selecting it (color x width relation to be designed though )
• add random colormaps
• if their is a string field enable coloring by that field
  (for example you can have a mapping str->int and then user can use random colormap)

point 2 and 3 in 4.10.m.

point 1 in 4.10.n for the color only. If a hex is detected. used it (start with #)

There is still no way to select a width and the minWidth is used for all links. i'm not sure how I can do both at the moment...
