bug killing! gnocl::text

Thanks to DMc for bug reports on the latest NB. Solved an issue arising from the gnocl::text search function, the interpreter would crash if the -tags option was not passed. This is now sorted and works well. The updated source and 32Bit linux builds are now available from SF.

Here's a test script.

# the next line restarts using tclsh \
exec tclsh "$0" "$@"

package require Gnocl

set box(1) [gnocl::box -orientation vertical]

set find [gnocl::entry]
$find configure \
    -primaryIcon "%#Clear" \
    -secondaryIcon "%#Find" \
    -variable findString \
    -onIconPress {
        switch %p {
            primary {
                set findString ""
                $txt tag delete tag_find
            secondary {
                $txt tag delete tag_find
                $txt tag create tag_find -foreground red
                $txt search $findString -tags tag_find

set txt [gnocl::text -wrapMode word]
$txt lorem

$box(1) add $find -fill {1 0}
$box(1) add $txt -fill {1 1} -expand 1
gnocl::window -child $box(1)
