Registration of Wookie widget list not refreshed

[GoogleCodeExporter]

The WookieServerConnection now gets the widgets from the Wookie server only 
once. This leads to a number of problems, most notably:

- When a new widget is deployed in the Wookie server after the first connection 
has been made between Simal and the Wookie server, it won't be fetched by 
Simal. It appears in Simal as if the new widget is not there.
- If the Wookie server is stopped this won't be noted by the 
WookieServerConnection. The cached list of widgets is still displayed on the 
ToolsPage (in the admin section), but with broken images.
- The new 'add project' link in the menu will not change in a link to the 
doapcreator widget if this widget is deployed in the Wookie server after the 
initial list of widgets has been fetched.

The only workaround for all these cases is to reboot Simal. 

A solution can be to refresh the widgets list when loading the ToolsPage, or 
provide a 'refresh' button on that page to refresh the list on demand.

An extra problematic scenario is when the widget had been deployed but is later 
removed from the widget server. Because the list of widgets is not refreshed 
Simal thinks the widget is still there, even though it's not. (Issue 358)
