Bug 1161195 - Part 1: Set java class names at compile time. r=nalexander

Rather than hardcoding the following classes in AppConstants.java.in and AndroidManifest.xml, they are set in
confvars.sh:
   org.mozilla.gecko.GeckoApplication (Specified using MOZ_ANDROID_APPLICATION_CLASS)
   org.mozilla.gecko.BrowserApp       (Specified using MOZ_ANDROID_BROWSER_INTENT_CLASS)
   org.mozilla.search.SearchActivity  (Specified using MOZ_ANDROID_SEARCH_INTENT_CLASS)
