Seven actions were absent from display_help(). This meant that commands like ':help ^P' did not work. They now refer to general.txt, but are not all described there. For two actions, generic-copy/paste, the file name was misspelled. This solves Github issue #44. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
