[latexila] Register custom stock icons from icon-names

[Sébastien Wilmet <swilmet src gnome org>]

commit a3762d0dc75eb954405b4c7565bec5dd69561ed1
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Sat Dec 27 11:01:37 2014 +0100

    Register custom stock icons from icon-names
    
    Don't list the icons from the GResource, because a later commit will put
    the custom icons in the GResource to sub-directories for each size
    (24x24, 16x16, etc), so it'll be more difficult to list all the custom
    icons.
