fix build of WebKit on 64-bit MSVC 2010

The following link was used as a reference (with adaptations for static build)

ignore untracked files generated during the build
do not build the QtWebkit tests
msvc: link to multithreaded static CRT + suppress warnings C4099, C4100, C4189

This is based on the corresponding commits in phantomjs:

https://github.com/ariya/phantomjs/commit/c3b30ac13654509b2fb3bfbf54789b885eff81a8
https://github.com/ariya/phantomjs/commit/d2c3a078ab50a8abd4b588744416ebfbfe2f905c
msvc: disable incremental linking for debug builds

This is because QtWebkit fails to link on 32-bit Windows.
