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.

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".

By default now only the first letter is case-sensitive. It is still
possible to choose full or no case-sensitivity as well.

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

They should always use the function parameter tooltip.

This fixes a bug where you were offered completion for
C foo( -> C foo(int x)
if C had a constructor taking int x.

You now get the function parameters as a completion suggestion when
declaring or defining a function. The tooltip for function calls
is unchanged.
