Briefcase: Need for manual install of unlimited-strength JCE is a support headache

What steps will reproduce the problem?
1. Create and use an encrypted form as per the instructions.
2. Install Briefcase.
3. Download and attempt to decrypt encrypted submissions.

What is the expected output? What do you see instead?

You expect decryption to work. Instead, in the vast majority of cases, it gives an
"illegal key size" error. This is because the user's JRE installation needs to be manually
upgraded with the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction
Policy Files. This is a serious pain.

Would be nice for Briefcase to have an installer that automates or at least semi-automates
installation of the necessary files. Alternatively, might default to weaker encryption
and allow users to specify stronger encryption once their JRE's have been upgraded.
(As it stands, users in export-restricted countries can never use ODK encryption unless
an option for weaker encryption is allowed.)

Needs a full ODK team discussion to decide.
