run-and-pause -> textpause

Attached is anew "textpause" script based on the run-and-pause script
supplied with menu-tiny. Instead of running commands and displaying their
output, it accepts filenames and displays their contents. The special
filename "-" allows stdin to be displayed, which means that the
run-and-pause command can be changed from:

    run-and-pause 'command'

to

    command | textpause -title 'command' -

The latter is longer but the textpause script is more generally useful, for
instance:

    at 08:30 "beep; textpause /tmp/wake_up_call"

to set a simple reminder.

Cheers,
