• Allow jar processing to take a regex of which classes to extract (--jarfilter)
• Tidy errors
• Push returns early when reordering to make control flow as simple as possible. Explicit support for ternaries which jump in to identical returns. (improves quality of some dex2jar code).
• Shrink catch block if it's over aggressive.
• Improve trailing goto removal once code at structurable stage.
• Handle conditionals that jump straight into a fall through (was leaving a goto)
• Don't allow static initialiser to be marked as an override (oops!)
