C#: added a check in LZOvl.Support to make sure the 'compressed size' is correct (fits within the given file).

C#: removed the BitConverter reference in the Huffman decompressor, and replaced the call with one to a local utility method (to be sure that the byte*->u32 conversion always uses the correct endianness.

C#: Extended the generic Supports(Stream) method with the length of the input stream, since Overlay-LZ compresses from end to start.

C#: Fixed the writing of the header of the RLE compressed files; it should state the decompressed size, and not the compressed size. Also added an exception that indicates there is still some input data to read after the compressed stream.
...
The current RLE implementation passed the first test: compression->decompression resulted in the same file for a manually created test file. (and the compressed file also has the expected format)

C#: Re-implemented the RLE decompression in the new format. The new format file has not been added to the project file, as I can only work in VS2010 where I am at the moment (and manually editing the file seems to break the autorun every time I try it).

C# (previous one as well): re-implemented the LZ-0x11 algorithm in the new structure. Also updated the GBATEK-like format description of the format, hopefully correct this time.

The start of an attempt to make this program structured better, as well as for easier addition of more formats AND compression for supported formats.

Augh. idiot-bug fixed. (the last 0xC bytes of arm9.bin should be ignored, no the first ones)

Last adjustment to the LZ-Overlay decompression for now, until I can compare a properly decompressed file with one that doesn't come out right with this program.

Added support for compression used in overlay files of the DS, as well as the arm9.bin file. The format is mostly LZ-0x10 in reverse, but has a small difference in the calculation of the Disp value for compressed blocks. The complete file also need not be compressed.

Added a built version of the C# project, since I'm apparently not allowed to create new downloads at the moment. =/
...
Also, an afterthought on the previous commit: I've also added an option to disable the use of specific decompression algorithms via the command line.

Added a new compression format in the C# source: type 0x40 LZ77/LZSS. It differs not very much from type 0x11 in compression size, but has an odd way of storing which blocks are compressed.
...
A Java-version of the scheme may come at a later time.
I _think_ this is a built-in compression, but it could also be a format Camelot made and used only for the latest Golden Sun installment.
Oh, I've also added the MIT licence to the C# source code file.

Note that the Java algorithms are a port of the C# ones, and only the LZ10 and LZ11 have been tested of the Java implementation.
