[Scidvspc-users] Switch between Current Side, Opposite Side and Both Sides wrt MainPV Moves Visualisation

[C H. M. <han...@gm...>]

Hi Steve,

This is a patch which allows users in Sequential analysis boardType
mode, to switch between looking at only Current side-to-move moves or
only Opposite side moves or both sides moves from the MainPV of the
engine on the analysis board.

Thus giving more flexibility wrt what one may want to look at from the
analysis engine's mainpv, also indirectly allowing one to probe more
into the mainpv without cluttering the board.

Inturn to help with the same, a listbox is shown next to the analysis
board in Sequential mode. So that user can switch between these views.

NOTE1:  I have also cleaned up the space-tab usage to be consistent
wrt the block of code in updateAnalysisBoard wrt boardVisualiseMoves,
to only use spaces.

NOTE2: Given that "1st moves from all multiPVs" and "SeqOfMoves in
MainPV" are orthogonal to one another and useful to view parallely at
the same time. I would request you to reconsider your decision to have
them as independent/exclusive modes, which does not allow both to be
viewed at the same time. Do note that both types of arrows use
different colors, so it is visually clearly differentiable without any
confusion. Also one can always disable moves-sequence visualisation by
turning the spinbox down to 0, if needed, while the default of 3 also
doesnt clutter the board.
