We do not need this check anyway.

Don't complete the current item when pressing special characters (e.g. `;') if the completion is automatically triggered.

Original version looks fine to me, but fails to compile with e.g.
gcc versions Ubuntu 4.4.3-4ubuntu5 and Debian 4.4.4-6.

... with a little bit of refactoring.

But for some reason it does not seem to have an effect

This reverts commit 62b83fcf, which was about filtering 'ghost'
elements out like "Rectangle { id }", where id was parsed as a
UiObjectDefinition. Unfortunately, "anchors" also is represented as
an ObjectDefinition ... Anyhow, the original problem does not
occur any more, so we can just revert this.

Previously we're setting the properties of the items one by one, each
time potentially triggering an update of the view. Actually this
uncovered an error in the Filter, which was only reacting to the first
change and therefore didn't take the item type into account on first
load.

Instead, we now use our own QStandardItem class which can be used to
assign all values at once.
