[Chicken-users] Update of the sqlite3 egg

[Thomas Chust]

Hello,

yesterday I realized a really stupid mistake of mine in sqlite3:changes,
which I fixed. I also renamed sqlite3:call-with-temporary-statement to
sqlite3:call-with-temporary-statements and enabled it to create any
number of prepared statements (but the new function is still backwards
compatible with the old one).

As usual, the updated egg and documentation can be found at
        http://www.chust.org/projects/sqlite3.egg
        http://www.chust.org/projects/sqlite3.html

cu,
Thomas
