Update the text of the GPL-2 to the latest text

The text of the GPL-2 in LICENSE was old, had the old FSF address, and referred
to the LGPL as the "Library GPL" (it's been "Lesser GPL" for a while now). This
simply updates the text with the latest text of the GPL-2. Apart from
formatting, the FSF address change, and the Library->Lesser GPL, there are no
other changes.
