This change makes `.travis.yml` a little bit simpler.

Travis-CI currently [supports][1] the following `language` keys:

* C
* C++
* Clojure
* Erlang
* Go
* Groovy
* Haskell
* Java
* JavaScript (with Node.js)
* Perl
* PHP
* Python
* Ruby
* Scala

Without `language: java` you should have `install: ant` and `script: ant test` tasks - as I [commented][2]!
The `language` specifies mainly the test entry point:
* in `c` and `cpp`: `./configure && make && make test`
* in `node_js`: `npm test`
* in `java`: "If Travis could not detect Maven or Gradle files, Travis Java builder will use Ant to build it. By default it will use `ant test`"

IMHO if you have the correct `install` and `script` tasks then the value of `language` is irrelevant.
