Bring build-svn-deps-win.pl up-to-date. Serf will still not build as-is.

* tools/dev/build-svn-deps-win.pl:
  (set_defaults, SERF_VER): Upgrade serf dependency to 1.3.6.
  (PCRE_VER): Upgrade PCRE dependency to 8.35.
  (build_pcre): Disable recursion as it will cause stack overflows
                in PCRE tests.
  (check_vs_ver,
   build_httpd): Add support for Visual Studio 2013
