New feaures release 0.30

A new version with few new features:
* Added "repeat new", i.e. repeat unlearned cards = card's you haven't learned using the application. Good if you have actually learned them elsewhere as I often do.
* Used often with "repeat new", you can select in the preferences that you want the cards to be presented in a random order rather than always in the same (usually alphabetical) one.
* Support for reading files on Siemens mobiles that don't support the FileConnection API but have their custom file access. The file must be named lessons.pau.gz and be stored in the top folder.
* If your mobile doesn't support file access, you can embed a lesson file directly in the application - you put a file lesson.pau.gz into the MiniPauker.jar before you put it on your phone. You may do it by renaming the *.jar file to MiniPauker.zip, putting the lesson inside and renaming it back to end with .jar. In this case do not use the MiniPauker.jad file at all or, if it can't be installed without it, change in it the value of 'MIDlet-Jar-Size:' to correspond to the new size of the jar in bytes (but it may be difficult to find out the true size).
* Added help with detailed instructions for various functions of the app.
* Hopefully an improvement of keys allocation so it should be easier to use the app.
* Reading of stored session loads first 100 cards and then continues in the background (loading in chunks of 100 ) so that you can start working with those loaded so far. Good for slow phones like Siemens CX65, Siemens ME75. You can check the progress in main menu > statistics.
