Title: Push down into Gdms some methods from SourceContext

This adds three methods from SourceContext (in monomap) into Gdms:
* into ```DriverManager```:

```java
public Set getDriverFileExtensions();
public boolean isFileSupported(File file);
```
* into ```SourceManager```:

```java
public boolean isEmpty(boolean ignoreSystem);
```

See the javadoc for more information.
This takes care of the first part required in #18, the other one being removing SourceContext from monomap: @nicolas-f, this one is for you ;-)
