both org.thoughtcrime.redphone.util and org.thoughtcrime.securesms.util have a Base64 util class, however, other than whitespace changes, and the securesms one having a couple of extra methods, they are the same. This commit removes org.thoughtcrime.redphone.util.Base64 and anything referencing it now uses org.thoughtcrime.securesms.util.Base64 Closes #4294
