v0.3.2

• Allow the user to set a custom cache_prefix when creating EsiApp so the prefix are controlled by the user. Default value is still esipy
• Renamed EsiApp.force_update() into EsiApp.clear_cached_endpoints(prefix=None). Now clear_cached_endpoints only clear cache for the cache_prefix (either the one defined when creating EsiApp or the one given as parameter. All endpoints objects are recreated upon next call automatically.
