We need to remove LoginToken objects on remove as well as clear
Add a FIXME with the problem with the m2m_changed scheme
Make sure that the token column is unique
Rerrangement of lines done by the Android build tools
Remove trailing whitespace from the AndroidManifest.xml files
Various updates to the AndroidManifest.xml files

This includes:

- Moving <uses-sdk> to before <application>.

- Add an android:allowBackup="false" attribute; this is the safe
  warning until we can confirm that "true" would be safe.

- Raise android:targetSdkVersion="8" to android:targetSdkVersion="17"

- Remove android:debuggable="true", which is now set automatically
  when you do either a debug or release build.

These fix all the warnings in this file.
Add a view to check the login via a token
A fix to deal with generate_token now returning a string
Temporarily allow old login tokens to persist due to a Django bug
