Don't sort the global completion items when we have too many of them, instead
populate the completion box in a way where local symbols are showed before
global symbols.

To only run if the pound/hash sign is at the start of the line.

Should have gone into master, not into the 2.0 release branch.

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 fake tooltip duplication is not nice.

The problem was that for

Foo::Foo
(|)

when the user triggers completion at |, startOfLine() returns a token
that's not on the current line and not yet tokenized by that instance
of the BackwardScanner.

As a fix I explicitly ask the instance to tokenize up to the given
index.

This reverts commit 2a59d2ae.

Because apparently, while designing the Objective-C language, somebody
thought it was a world-class idea to allow any white-space between the
'@' character and the subsequent keyword. With this fix, we now
correctly parse:
    @  dynamic
and:
    @
      selector
and:
    @"foo"
     "bar"
    @"mooze"
(This last one is 1 single string split over multiple lines.)
Wonderful, isn't it?

What we (and Clang) do not support, but what GCC supports is something
like:
   @"foo"@@  "bar"  @"mooze"  @@
which is equivalent to @"foobarmooze".
