Refactor 4 PPB_Flash functions to the new PPAPI resource model.

The functions being refactored are:
-SetInstanceAlwaysOnTop
-DrawGlyphs
-GetProxyForURL
-Navigate

Each of these functions was manually tested with a Flash movie that uses it.

Navigate() was tested on:
-http://www.tjgames.com.br/jogos-online/169-Yan_Loong.htm
-http://www.flonga.com/play/zombotron2.htm
which were consistently causing instance deletion during a Navigate() call (causing https://code.google.com/p/chromium/issues/detail?id=165978).
