Enable support for the Mac OS X spellchecking service in chromium.

spellchecker_platform_engine.h provides a basic interface for
platform specific spellcheckers to follow. spellchecker_mac.mm
implements these functions for the OS X spellchecking service.
spellchecker_win.cc and spellchecker_linux.cc provide a space for 
future developments on these platforms. spellchecker_common.h 
contains a few shared variables and typedefs that are useful across
all spellchecking code. spellchecker.cc has been modified to 
call the SpellCheckerPlatform::SpellCheckerAvailable() and use
either hunspell or the platform spellchecker based on that
call. Many new test cases have been added to one of
the unit tests as well. chrome.gyp has been edited
to reflect the added files.
