Also some less significant improvements.

We need our very own syntax highlighter in Qt Creator.

Adds a generic Outline pane to the sidebar. The CppEditor & QmlJSEditor
plugins will implement the IOutlineWidget/IOutlineWidgetFactory interface to
provide views specific to C++/Qml/JS documents.

See BaseTextEditor::setRefactorMarkers(...). The markers support
a clicked signal via BaseTextEditor and tooltips. They feature
a cursor, but are always positioned at the end of the line (not block!).

As special gimmick they do extend the document width when they
are positioned outside the document area.

Generic highlighter: Interface for automatic download of available definitions. Refactorings and changes in related parts of the code.

Indenter is now a separate class which can be reused through composition. Added it to the generic editor.

By moving the completion settings into the TextEditor plugin, so that
both the CppTools and the QmlJSEditor plugins can access the settings.

The user-interface to edit the settings is still in the CppTools plugin,
since we're in string freeze at the moment. It should be moved to the
TextEditor plugin later.

For now the QML completion only supports the case-sensitivity and
partial completion options, since there is no automatic insertion of
brackets.

The Parentheses, TextBlockUserData and TextEditDocumentLayout classes
and their member function implementations were spread around the
BaseTextEditor class. Moving them to their own file to make the code a
bit better organized.

Trying to clean up a little.

It used to be hidden on the Display settings page.

Task-number: QTCREATORBUG-135

Moved Completion::getCompletion() in ICompletionCollector and made the filtering of completion items more C++ friendly.

As side effect we can now play a bit with visualizing extra selections

Task-number: 258468

With the new representation it fits fine, and this is a bit more
convenient for the user.

In preparation of being able to select from multiple color schemes.

Which nicely adds the occurrances to the search output window for
navigation.

Hopefully i didn't miss a plugin.

page of its own now

The page had grown too large so now the display settings have been split
off onto their own page.
