Make PurplePluginProtocolInfo definitions consistent

Since we can't use C99 structure initialisers, we have to manually add
new NULL fields to all protocols whenever we extend the structure.

Make it slightly easier to script that, by making the current last
field (get_cb_alias) consistent in all cases. In particular, there's
no reason *not* to have the trailing comma, as most already do.

Now I can add a new field to the PRPL by doing something like this...

PROTOFILES=`grep -rl '[A-Za-z_][A-Za-z0-9_]*,[[:space:]]*/\* get_cb_alias \*/' libpurple/protocols/ `
sed '/\/\* get_cb_alias \*\//{p;s/[A-Za-z_][A-Za-

* In Debian bug #271639, jwz says:
*
* Purple should simply ask xscreensaver how long the user has been idle:
* % xscreensaver-command -time
* XScreenSaver 4.18: screen blanked since Tue Sep 14 14:10:45 2004
*
* Or you can monitor the _SCREENSAVER_STATUS property on root window #0.
* Element 0 is the status (0, BLANK, LOCK), element 1 is the time_t since
* the last state change, and subsequent elements are which hack is running
* on the various screens:
* % xprop -f _SCREENSAVER_STATUS 32ac -root _SCREENSAVER_STATUS
* _SCREENSAVER_STATUS(INTEGER) = BLANK, 1095196626, 10, 237
*
* See watch() in xscreensaver/driver/xscreensaver-command.c.
*
* @return The number of seconds the user has been idle.
