Init all class member pointers to NULL.
This fixes possible crash on exit when dependent
plugin was not loaded (e.g. TextEditor was missing).
In this case plugin's constructor gets called,
initialize() method is _not_ called
and destructor gets called -> crash.

Properly delete dependent plugins on
a plugin which failed to initialize properly.

Fix labels of deleted plugins inside an error dialog
after pressing "Error Details" from "Installed Plugins"
dialog.

With every single change in a document the corresponding IndexItem
elements were extracted and put into an vector. The locator filters
then used these lists to iterate over and filter them.

This change removes that extraction, and the filtering now directly
iterates over the IndexItem elements with a callback.

The exception is the current document filter, because it also queries
for all declarations. Adding this to the model would result in a higher
memory usage, while that information is only used by this filter.
