Title: Explicitly specify 1.8 when installing jruby-18mode

Noticed this when running a build for resque

https://travis-ci.org/defunkt/resque/jobs/3498628

```
$ rvm use jruby-18mode
$ ruby --version
jruby 1.7.0 (1.9.3p203) 2012-10-22 ff1ebbe on Java HotSpot(TM) Server VM 1.7.0_09-b05 [linux-i386]
```

The default for rvm 1.17 when installing jruby is to build as 1.9.3.

This change just explicitly uses `--18` when installing `jruby` and renames it `jruby-d18`.
