Show help as showtip
This code was inspired by tooltip-help.el by Tamas Patrovics. Use `showtip' to replace the toolitp display code of `tooltip-help.el'. Show help information as showtip. When your text cursor in at a valid symbol, use function `sh-show-help' can get help information. `sh-show-help' will get different help information along with the type of current symbol. Now can support function, variable, face for emacs-lisp-mode.
