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.

the fix makes the mouse cursor visible when the editor loses focus.
This fixes an issue with the completion box, where on mac and windows
no mouse cursor would be visible (it worked on X11 due to the way
X11 does mouse grabbing for popup windows).

Introduce "Reset Font Size" action, bound to Ctrl+0

Remove overlap. Add extra selection tooltips for the cpp hover handler.

1. allow empty overlay selections
2. make it possible to bind a selection to a specified length

This is necessary since a recent change in Qt 4.6 to how the
WaveUnderline is drawn. It makes sure the WaveUnderline repeats
correctly from one text item to another.

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

Creator only indents the first line, and reindents subsequent lines relative
to the indentation change of said first line. This fails when the first line
contains no non-space characters. Solution in this change: skip (visually) empty
lines.

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.

at a later stage we will look into harmonizing context menu among different editors.
The cpp editor had the biggest need, because its context menu features all sorts of
extra refactoring operations, thus the standard Qt context menu became too large.

BaseTextEdit's paint event relied on us setting the line count of
invisible blocks to 0. This was not always the case, causing pixel
garbage to occur.

In combination with ifdef'ed-out blocks, the collapse block
indicator was sometimes painted with the ifdef'ed out color.

The changes enables the auto-parentheses magic of normal
backspace also for the DeleteStartOfWord case.

Also move Designer::Internal::FormWindowEditor ->

This implementation relies less on the pasted block of text having
a trailing newline.

auto-indentation of pasted text now only happens when complete
lines including a trailing paragraph separator are copied and pasted.

In addition, the reindent() functions ensures that the relative indentation
within the pasted block is preserved. This mechanism is now also used for
moving lines up/down.

when pasting text which ends with a newline, we should not
reindent the final line, instead we will preserve the indentation
that was there.

We now exclude brace in ifdefed out sections when calculating,
whether or not the braces match. This requires adjust the brace
levels whenever sections get ifdef'd out or ifdef'd in again.
