/**
* Returns the language-dependent label with the given key. The search order is to look first in
* the extension's <code>label</code> files and if the requested label is not found in the BlueJ
* system <code>label</code> files. Extensions' labels are stored in a Property format and must be
* jarred together with the extension. The path searched is equivalent to the bluej/lib/[language]
* style used for the BlueJ system labels. E.g. to create a set of labels which can be used by
* English, Italian and German users of an extension, the following files would need to be present
* in the extension's Jar file:
*
* <pre>
* lib/english/label
* lib/italian/label
* lib/german/label
* </pre>
*
* The files named <code>label</code> would contain the actual label key/value pairs.
*
* @param key Description of the Parameter
* @return The label value
