Detach ProguardConfiguration from InternalOptions as much as possible.

The following options are removed from InternalOptions:
* -keep rules
* -printseeds
* -printusage
* -printmapping
* -obfuscationdictionary
* -classobfuscationdictionary
* -packageobfuscationdictionary
* -flattenpackagehierarchy
* -repackageclasses
* -dontwarn

Also, make immutable data, such as obfuscation dictionaries,
indeed immutable.
