Add WIP .client and .service files.

These are roughly what need to get installed to make the approver (the
little dialog box that pops up for incoming offers) and handler
(LibreOffice itself) service-activatable.

Without these, your contacts will only see that you're capable of
LibreOffice tubes while you're running LibreOffice, and you won't get
a prompt unless liboapprover is running.

 To enable configure LibO with --enable-telepathy
 
+If you have a Telepathy-enabled LibreOffice installed to /usr (including
+liboapprover) you may also want to install the .service and .client files to
+make everything service-activatable:
+
+    mkdir -p $HOME/.local/share/telepathy/clients
+    ln -s $PWD/tubes/LibreOffice.client \
+          $PWD/tubes/LibreOfficeApprover.client \

+    mkdir -p $HOME/.local/share/dbus-1/services

+          $PWD/tubes/org.freedesktop.Telepathy.Client.LibreOffice.service \

+
+Otherwise, you need to make sure liboapprover and a Telepathy-enabled
+LibreOffice are running.
