Added new alpha channel colorspace constants/pixel formats, so applications can specify that they need the unused byte in a 4-component RGB output buffer set to 0xFF when decompressing.

Add new API functions, tjAlloc() and tjFree(), which allow memory to be allocated and freed using a method of the library's choosing. At the moment, the primary purpose for this is to avoid allocating/freeing memory across the DLL boundary on Windows.

Completely refactored the TurboJPEG C API so that it uses pixel formats instead of the clunky pixel size + flags combination to define the pixel size and component order. tjCompress2() and tjTransform() can also now grow the JPEG buffer as needed, which can allow programs to save memory by not pre-allocating the "worst-case" buffer size calculated by TJBUFSIZE(). Converted API documentation to Doxygen. There is no legacy code remaining, so the refactored version of the library has been re-licensed under a BSD-style license.
