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-

/*
This example demonstrates how to use libpurple-client to communicate
with purple. The names and signatures of functions provided by
libpurple-client are the same as those in purple. However, all
structures (such as PurpleAccount) are opaque, that is, you can only
use pointer to them. In fact, these pointers DO NOT actually point
to anything, they are just integer identifiers of assigned to these
structures by purple. So NEVER try to dereference these pointers.
Integer ids as disguised as pointers to provide type checking and
prevent mistakes such as passing an id of PurpleAccount when an id of
PurpleBuddy is expected. According to glib manual, this technique is
portable.
