Clean up the README a bit (google#1376)

* Remove a lot of "Gson" as it's implied nearly everywhere.
* Remove broken Javadoc badge. Move other badges to be near the content to which they apply
* Not an official Google product
* Make download section more general. People other than Android developers use Gradle, for example.

+# Gson
 
 Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object.
 Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.
 
 There are a few open-source projects that can convert Java objects to JSON. However, most of them require that you place Java annotations in your classes; something that you can not do if you do not have access to the source-code. Most also do not fully support the use of Java Generics. Gson considers both of these as very important design goals.
 
-### Gson Goals
+### Goals
   * Provide simple `toJson()` and `fromJson()` methods to convert Java objects to JSON and vice-versa
   * Allow pre-existing unmodifiable objects to be converted to and from JSON
   * Extensive support of Java Generics
   * Allow custom representations for objects
   * Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types)
