select a couple plugins by default

[Paolo Borelli]

It's is useful to have one or two plugins on by default, for at least two reasons:

- some of them are really useful to a large set of users
- it's a good band aid to the "empty tools menu" problem

FC is going to ship a similar patch:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=131607

I am also going to discuss such a solution upstream (see
http://bugzilla.gnome.org/show_bug.cgi?id=153068), but in the mean time it
sounds like a useful patch to include.

For the Live CD version of Ubuntu I think it is essential that (almost) all
plugins be enabled by default, but hopefully this can be dealt with upstream
before the next major release

[Sebastien Bacher (seb128)]

this bug is fixed with gedit 2.9.1 in hoary:
"- enable some of plugins by default. The way active plugins are stored in
  gconf changed, you may have to re-select some of the plugins "

The list of plugins is: docinfo,spell,time
