Use JavaDoc comments for functions, variables description

[vovkab]

Please use JavaDoc comments, to describe functions, variables and etc in your code.
Right now you use comments, which are obviously not a javadoc comments, and you can't get description of functions with this way.

Here how it looks right now:
/* Broadcast when the api has successfully connected to the server.
* You may now call enableBumping to enable bumping and matching.
*/
public static final String CONNECTED = "com.bumptech.api.connected";

Should be:
/**
* Broadcast when the api has successfully connected to the server.
* You may now call enableBumping to enable bumping and matching.
*/
public static final String CONNECTED = "com.bumptech.api.connected";
