If there are less than 256 colors in the piskel, do not perform anycolor
quantization, just reuse the colors from the piskel.
Added preserveColorsParameter to gif.js library.
If nb colors>256, fallback to the previous behavior. This could be
improved by checking the number of colors for each frame. The palette is
defined independantly for each frame, so as long as a frame is <256
colors, we could reuse the original colors.
I also believe that images with more colors would get a better quality if
we could use a single color sample for all frames. This would avoid color
'gaps' as we can experience today. In any case, for piskel, < 256 is a
reasonable assumption
Created dynamic palette displaying currently used colors.
This palette is now selected by default.
New service UsedColorsService created. Listens to PISKEL_RESET and
TOOL_RELEASED and keeps track of the list of current colors.
Still need to :
- improve sorting of colors
- allow to clone the current color palette as a custom palette
- add proper getter in UsedColorService to get the list of current colors
Also I hardcoded a max-height for the palettes-list as I found no better
way of handling the case of palettes containing many colors.
Maybe should add a limit to the number of colors handled by this automatic
palette.
Mousemove events do not have the correct button information
Need to keep the state of which button is clicked at which moment
This was actually the initial implementation ...
But I removed it because I couldn't remember why we did this in the
beginning.
Added lots of 'warnings' in comments, but won't be safe until we get good
integration tests.

"What if multiple buttons are pressed during mouse move? And how does the
integer field (button) indicate that no button is pressed? I think this
should be wontfix -- if people need button information during mouse move events
we need a new way of getting it (buttonSet), not the same way it works for click,
etc."

- Fixed : manager UI is redrawn after save
- the Selected palette is saved as a user preference
- default background is now the dark one
- the selected palette is not reset after closing palette manager
