v0.2 beta 1 release

It's there. I packed my current build and released it to the public. It has all the basic features of what will make v0.2 fantastic. Grab it, now.

Note that this is a beta version, so the bugs may occur.
Also, there are a few features which haven't been implemented in this version yet.

- Log saving
- Program and Help menu

Things that did made it in this release include:

- Importing sudokus
- Better solving algorithm (added Hidden Pairs and Naked Triples techniques)
- The new swing GUI, which is a huge improvement.
- Intelligent error marking system
- ...

Please post feedback in the tracker system the boards.
