Review request for Kate and KDevelop.

Description
-------

This patch provides a new completion model which gathers items from the syntax files. It simply suggests all words which are listed as keywords for the highlighting context which is active at the position where completion was invoked.

To avoid storing all the places where the highlighting context changes, an option was added to the function which calculates the highlight, which allows to optionally get all the context changes in a QVector. When completion is invoked, the current line is re-highlighted, and the context switches are extracted; from that the highlighting context at the cursor position is determined. The keyword items from this context become the items of the completion model.

An option is provided in the settings dialog to turn this new model off.
