Added -append flag to db_multirow. Works like the "template::multirow
append" command. EX:
So in the templates query interface you do:
template::multirow create ...
template::multirow append ...
Now you do:
db_multirow foovar ... (first or only multirow)
db_multirow -append foovar ...
Setting of new array variables is supported in the code block on the
db_multirow command using "set foovar(new_array_var) "value"" syntax
