Compile twittering-mode.el

[humitos]

Hi,

Not sure if relevant, but when I compile it from github master with this command:

emacs -Q --batch -l "~/.emacs" -f batch-byte-compile packages/*.el 2>&1 | grep -C 4 "Error"

I get:

packages/twittering-mode.el:10122:39:Warning: ‘interactive-p’ is an obsolete
    function (as of 23.2); use ‘called-interactively-p’ instead.

In twittering-stop:
packages/twittering-mode.el:10277:21:Error: missing value for ‘twittering-idle-timer-for-redisplay’ at end of setq

In twittering-initialize-global-variables-if-necessary:
packages/twittering-mode.el:10534:18:Warning: reference to free variable
    ‘twittering-sign-string-function’

BTW, the mode works properly anyway.
