Title: Serve documentation for gems in all gem paths.

Hi,

I found that gem server has issues, when running

```
$ GEM_HOME=foo gem server
ERROR: While executing gem ... (ArgumentError)
foo does not appear to be a gem repository
```

This pull request fixes this issue and on top of that, it allows to serve documentation for all gem paths.
