Test edition #2

This release adds .ppx subfile extraction and addition.
Some notes about this release:

• Direct editing of subfiles is still not supported, meaning you'll have to manually extract the files to edit them and re-add them afterwards.
• The version of ppx embedded in this version uses a "delta" method of compressing instead of a traditional recompress of everything, so that (hopefully) all files that are already compressed and encoded are not recompressed, meaning a lot faster save time.
  • The delta appender is currently very weak and will not handle large additions of files (>~16mb) very well, so keep that in mind when you add large (or large amounts of) files to the archives.
• Adding .xx files currently does not work properly, and most likely will cause you to lose your changes in your opened .ppx file.

Test edition #1

More of a release to show that it actually builds, currently only opens .ppx files and is unable to do anything else with them.
