Added 'setFont' and 'setAnchorPoint' to CCEditBox

Now CCEditBox has an ability to change its font and size, and also it is working fine now with 'setAnchorPoint' on iOS which wasn't working properly.
The changes are applied to the bundle test project and tested on iOS and Android.
ps) Because there was a linkage error on Android build with the test project with its default setting, I needed to add 'APP_ABI = armeabi-v7a' to Application.mk. I'm using ndk-r7b.
