- change fonts (new one is Proxima Nova Alt Condensed Regular.otf)
 - add 'edit' icons next to subpatterns names
 - add 'add pattern' in patterns.component.html
 - add 'delete subpattern' option
 - on pattern name click, its subpatterns are automatically shown
 - show one pattern details at a time in the tree view
 - 'show prefixes URI' is now a modal
 - add 'add-triple' modal : adds a triple to the selected subpattern. Autocomplete works fine (hopefully) for selecting subjects, predicates and objects.
 - reload graph when a new triple is added

The patterns edition doesn't work on DBPedia.
