- 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.

The snapshots at the moment of search were held as long as the
corresponding search result panel was kept, to allow mapping of the old
symbol to the corresponding symbol in the new snapshot.
Now we just save the file name and ID of the old symbol.

These not only take less space than UTF-16 encoded QStrings, but due to
the caching in the CppEditorSupport also take less time to build.

This patch also fixes a number of possible encoding issues, where files
and constant strings were (falsely) assumed to be UTF-8.

This change
* Removes IMode::type, ModeManager::activateModeType, and
  IEditor::preferredModeType, and adds IEditor::isDesignModePreferred
  instead
* Adapts the mode switching code in EditorManager to handle multiple
  windows, for example switching to edit mode should only happen if
  the editor/view is in the main window. Otherwise the editor window
  should be raised and focused
* Renames EditorManager::NoActivate --> DoNotChangeCurrentEditor
* Reverts the EditorManager::ModeSwitch logic to switch mode or
  make the current editor visible by default, introducing
  DoNotMakeVisible flag instead
* Fixes a few instances where EditorManager::ModeSwitch should have been
  used

One non-trivial problem left: If you open a .ui file and switch to an
external editor window, edit mode is activated, because the current
editor no longer is a .ui file, which means that the design mode gets
deactivated.

When making a case insensitive search, try to keep the string capitalization when doing
the replace:
      - All upper-case matches are replaced with the upper-case new	text.
      - All lower-case matches are replaced with the lower-case new text.
      - Capitalized matches are replace with the capitalized new text.
      - Other matches are replaced with the new text as provided.

Note: this does not work with regexp replace, only plain text.

If the result lines contain non-Latin1 characters (e.g. in comments),
the output is garbled. Using QByteArrays with toUtf8() and fromUtf8()
doesn't seem to be an alternative, as in this case the macro.offset() is
no longer valid.

So it seems to be the best to use QString for the result lines.
