[gnome-latex: 117/205] Open document: verify if the doc is not already opened

[Sébastien Wilmet <swilmet src gnome org>]

commit 7084ec9555eb213845391a4ee2834dab95313fec
Author: Sébastien Wilmet <sebastien wilmet gmail com>
Date:   Tue Nov 10 19:30:12 2009 +0100

    Open document: verify if the doc is not already opened
    
    We traverse the GList latexila.all_docs and compare all the filenames.
    If a document is already in the GList, we switch to the corresponding
    tab on the notebook (which have the same numerotation).
