Version 5.10 beta 1

1. Added extraction support for ZIP and ZIPX archives using
BZIP2, LZMA and PPMd compression.

2. Added extraction support for 7z split archives
(.7z.001, .7z.002, ...).

3. Added support for AES-NI CPU instructions allowing to improve
RAR encryption and decryption performance.

4. Default theme images are scaled up with better quality
in high DPI display mode.

5. Environment variables, such as %temp%, can be used
in "Files to add" field of archiving dialog.

6. Switch -ai can be used when creating RAR archive,
so predefined values, typical for file and folder,
are stored instead of actual attributes.

Previously this switch could be used only when extracting.
