RFS: proguard/5.0-1

[Emmanuel Bourg <ebourg@apache.org>]

Hi all,

I updated proguard to the latest upstream release and I'm looking for a
sponsor to upload it. This update fixes another Java 8 transition issue.

Here is the changelog:

  * New upstream release (Closes: #754964)
    - Increased the source/target level to 1.5
    - Depend on java5-runtime instead of java2-runtime

Thank you,
