[Config] Mode configuration added.

src/Gargantext/Config.purs

+{- | Main Configuration of Gargantext Front-End
+
+The main function to use for internal link in the Front-End
+developpement is : toUrl.
+
+* Example usage:
+- for Mock config:
+    - toUrl Corpus 3 == "http://localhost:2015/corpus/3"
+    - (this mode supposes you have the mock haskell backend running)
+
+- for Dev config:
+    - toUrl Corpus 3 == "http://localhost:8008/corpus/3"
+    - (this mode supposes you have the dev haskell backend running)
+
+- for Prod config:
+    - toUrl Corpus 3 == "http://gargantext.org:8080/corpus/3"
+    - (this mode supposes you have a prod haskell backend running on the specified url)
