weechat: split plugins into separate outputs

Also add a wrapper generator that allows adding the plugins back
conveniently and corresponding documentation in the package notes
section of the nixpkgs manual.

<para>
Weechat can currently be configured to include your choice of plugins.
To make use of this functionality, install an expression that overrides its configuration such as
<programlisting>weechat.override {configure = {availablePlugins, ...}: {
plugins = with availablePlugins; [ python perl ];
}
}</programlisting>
</para>
<para>
The plugins currently available are <literal>python</literal>,
<literal>perl</literal>, <literal>ruby</literal>, <literal>guile</literal>,
<literal>tcl</literal> and <literal>lua</literal>.
</para>
<para>
The python plugin allows the addition of extra libraries. For instance,
the <literal>inotify.py</literal> script in weechat-scripts requires
D-Bus or libnotify, and the <literal>fish.py</literal> script requires
pycrypto. To use these scripts, use the <literal>python</literal>
plugin's <literal>withPackages</literal> attribute:
<programlisting>weechat.override {configure = {availablePlugins, ...}: {
plugins = with availablePlugins; [
(python.withPackages (ps: with ps; [ pycrypto python-dbus ]))
];
}
}
</programlisting>
