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".

 * Remove duplicate headers.
 * Move own headers to the top.

Syntax highlighting for Objective-C identifiers (super, self, nil, Nil, _cmd, SEL, IMP, BOOL, YES, NO, id).

Introduced T_CPP_COMMENT and T_CPP_DOXY_COMMENT to handle C++-style comments and improved CPPEditor::isInComment to handle the newly introduced tokens.

As side effect,this change should fix the regression we introduced in the "automagically" quote/brace insertion.

Things you mustn't do:
1) end an enum with a comma

2) #include <cxxxx> and not use std::

3) use anonymous structures

All three things are invalid C++. Anonymous structures inside
anonymous unions are allowed by GCC, but that doesn't mean it's valid.
