Changed prepare_dependencies.py so that it runs entirely off cmake for easier setup and processing of library for BlackBerry
service APIs compile now
-Fixed missing BLACKBERRY define
-Fixed GLogPackageInstaller issue where it only installed the library instead of the include files
-Fixed issue (more like ignore) where http_transport_test_fixture.cc called "EXPECT_DEATH" which may have been removed from gtest
-Fixed issue where File::RecursivelyDeleteDir used the Linux-specific version of readdir_r (not 100% correct right now, working on it)
