This patch fixes typos in the files that generate xnee.sh.

One typo I did not fix is the use of "nr", as in:

########################################################################
#
# Function name:    xnee_fake_button_press
#
# Arguments:        integer nr
#
# Return value:     none
#
# Description:      Fakes press of button 'nr'

"nr" is not familiar to English readers. Did you mean "number"? If so, write that.

When you say "button" here, do you mean "mouse button"? If so, it would be clearer if you write that.
