The new action "load deleted game" loads a recently deleted game from
the autosave file, without affecting the "last used file" and "current
position in last used file" properties.
The 20 most recently auto-saved games are kept in the file
DroidFish/pgn/.autosave.pgn.
Overwriting an existing game when saving a new game also auto-saves
the old game.
The analysis information is copied as text to the clipboard. The full
text is copied, so the "truncate variations" and "hide statistics"
settings have no effect on the text put in the clipboard.
Add new setting (default true) to allow input of moves by dragging a
piece from its source square to the target square.
This setting partially overlaps with scroll gestures on the chess
board, so when this setting is enabled, scroll gestures will only
happen if the starting square is empty or contains a piece of the
color not to make the next move.
After the engine plays a move in a game, a thread could get into a
state where it would poll for engine output every millisecond while
waiting for the human player to make the next move.
Even though this was not a busy wait, it would still use more CPU
resources than necessary, so the logic has been changed to prevent
this situation.
Move the margin between the move list and the button row to the button
row container, so that the margin does not interfere with the
calculation in MoveListView.onMeasure().
Adjusted the MoveListView content size so that the last row can be
scrolled to a position where the previous line is completely hidden.
When computing the autoscroll Y position the parts of characters
descending below the font baseline were visible for the line before
the first line that was supposed to be visible.
Also add a small margin above the move list to separate it somewhat
from the button row.
En passant fixup requires generating a list of legal moves, which can
fail with an array index out of bounds exception if there is a pawn on
the first/last rank.
