qdoc: Fixed broken TOC links to Reimplemented sections

This update fixes some links in the table of contents on class
reference pages. Links to sections of reimplemented functions did not
work because the word 'reimplemented' was not included in the anchor.
This update fixes that bug.

MSVC: Restore 'public' accessibility of QMetaType member functions

They were made 'private' as a side effect of a change enabling
support of template friends for MSVC. However, accessibility
is part of the MSVC's name mangling and thus BC was broken.

[ChangeLog][Important Behavior Changes] Restored binary
compatibility with Qt 5.3.2 on Windows when using MSVC 2012 or
MSVC 2013. This means that Qt 5.4.1 is no longer binary compatible
with Qt 5.4.0 when using either of those compilers.
