When automatic insertion of brackets is disabled in the completion
settings, it is reasonable to expect the automatic matching of brackets
is also disabled.

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.

We now use two cursors, with the first one being positioned at the
character before the find scope starts. This makes it possible
to extend the scope when typing at the beginning or the end of
it. This is more what the user expects. The effect is noticable
with find&replace of words at the beginning or end of the scope.

Fixed colors to use the same as refactoring rename, and a few
fixes for undo and document changes outside the tab areas.

It activates too easily for some people.

Convenient when you don't want to see all the big license headers.

The extra area only updated the current *line* when the cursor moved, not
the entire paragraph. This left bold line numbers behind. The fix adds
the required update region when the cursor position changes blocks.

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

Only checking Ctrl and link availability on mouse release was triggering
the navigation too easily.

Now you have to press and release the mouse on the same link, having
Ctrl pressed all the time. In addition, when changing the text selection
the link is also cleared.

The BaseTextEditor was unconditionally setting the mouse cursor on each
mouse move event, after which the CPPEditor would set it as well when
the mouse was above a link. This caused some mouse cursor flickering, so
now the cursor is only set when it's supposed to change.

Also fixed an issue where the link wasn't removed when leaving the text
editor with the mouse while Ctrl was pressed.

Introduce setCodeFoldingSupported to the BaseTextEditor, and only
enabled it for the C++ and QtScript editors. This removes the useless
margin meant for code folding markers from the plain text editor and
.pro file editor.
