- fix memory leak in find-usages
- do not retain snapshot in search history
- when an editor is invisible for more than 2 minutes, release the
  backing snapshot

Retaining snapshots will retain their documents, and if done for too
long, the memory consumption might grow. This is especially the case
when switching to a different kit (Qt version): in that case, the new
versions of headers will be indexed, while the old ones stay around.

This patch also fixes a number of possible encoding issues, where files

Both semantic highlighting and code-completion go hand-in-hand, so now
the ModelManagerSupport class acts as a "factory" for the model manager.
Depending on the mime-type of the document in the editor, the model
manager will return the appropriate highlighter or code-completion
engine. If none is registered, the built-in fall-back is used.

annoying.
