[gnome-latex] latexila -> gnome-latex migration: migrate personal templates

[Sébastien Wilmet <swilmet src gnome org>]

commit 9538491ed07e09d69e1984bf3c3ca85892c9156a

    latexila -> gnome-latex migration: migrate personal templates
    
    The group name for the RC file was "LaTeXila", so it needs to be
    changed. But change it to a name independent of the application.
