Added a python script to update the description of stickers

updatePacks.py

+import json
+import sys
+
+# Check the arguments
+# Pack is updated only if index and description are precised
+update = False
+if len(sys.argv) <= 1 or len(sys.argv) == 3:

+    exit(1)
+elif len(sys.argv) > 3:
+    update = True
+
+# Read the pack file
+with open(sys.argv[1],'r') as myfile:
+    stickerpack = myfile.read()
+
+# Parse the pack
+json_pack = json.loads(stickerpack)
+nb_stickers = len(json_pack['stickers'])
+    
+    
+if update == False:
+    # Print the number of stickers in this pack
+    print("There are " +str(nb_stickers) + " stickers in this pack: ")

+    exit(0)
+
+# Informations

+new_body = sys.argv[3]
+
+
+# Change the body of the sticker_index
+if sticker_index > nb_stickers:
