Subject: puzzles: refactor and resync with upstream

This brings puzzles up-to-date with upstream revision
2d333750272c3967cfd5cd3677572cddeaad5932, though certain changes made
by me, including cursor-only Untangle and some compilation fixes
remain. Upstream code has been moved to its separate subdirectory and
future syncs can be done by simply copying over the new sources.

-Fill in the grid with the letters shown to the top and left of it, so
-that the full grid is a valid

-<p>
-If you don't already know what a group is, I don't really recommend
-trying to play this game. But if you want to try anyway, the above is
-equivalent to saying that the following conditions must be satisfied:
-<ul>
-<li>
-<strong>Latin square</strong>. Every row and column must contain
-exactly one of each letter.
-<li>
-<strong>Identity</strong>. There must be some letter <i>e</i> such
-that, for all <i>a</i>, the letter in row <i>e</i> column <i>a</i> and
-the one in row <i>a</i> column <i>e</i> are both <i>a</i>. In the
-default mode, this letter is always <i>e</i> and its row and column
-are filled in for you; by reconfiguring the game using the Type menu,
-you can select a mode in which you have to work out which letter is
-the identity.
-<li>
-<strong>Inverses</strong>. For every letter <i>a</i>, there must be
-some letter <i>b</i> (which may sometimes be the same letter
-as <i>a</i>) such that the letters in row <i>a</i> column <i>b</i> and
-in row <i>b</i> column <i>a</i> are both the identity letter (as
-defined above).
-<li>
-<strong>Associativity</strong>. For every combination of
-letters <i>a</i>, <i>b</i>, and <i>c</i>, denote the letter in
-row <i>a</i> column <i>b</i> by <i>d</i>, and the one in row <i>b</i>
-column <i>c</i> by <i>e</i>. Then the letters in row <i>d</i>
-column <i>c</i> and in row <i>a</i> column <i>e</i> must be the same.
-</ul>
-<p>
-To place a letter, click in a square to select it, then type the
-letter on the keyboard. To erase a letter, click to select a square
-and then press Backspace.
-<p>
-Right-click in a square and then type a letter to add or remove the
-number as a pencil mark, indicating letters that you think
-<em>might</em> go in that square.
-<p>
-You can rearrange the order of elements in the rows and columns by
-dragging the column or row headings back and forth. (The rows and
-columns will stay in sync with each other.) Also,
-left-clicking <em>between</em> two row or column headings will add or
-remove a thick line between those two rows and the corresponding pair
-of columns (which is useful if you're considering a subgroup and its
-cosets).
