Insert Open/Close Tag (With Current Word)

# This script will expand the current word into: <word></word>
# It will recognize HTML 4.0 tags that need no close tag.
#
# With no current word, it will insert: <p></p> and allows you
# to overwrite the tag name and add potential arguments.
#
# The result is inserted as a snippet, so it's
# possible to tab through the place holders.
