[BOOTDATA] Use a Win2k3-compatible TXTSETUP.SIF layout for the specification of the files list.

Also add detailed documentation about the meaning of each field, obtained from:
- my own tests;
- http://www.msfn.org/board/topic/125480-txtsetupsif-syntax/
- http://www.msfn.org/board/topic/127677-txtsetupsif-layoutinf-reference/

In addition, add a spreadsheet that helps generating the files list.

Note that the files source directory is "\reactos", until we use
per-architecture directories in the installation medium.
