added scripts to generate datasets and icon-textures for the talent-calculator

that should make everyone with some client-mods or custom database entires happy

removed previously supplied datasets (which were partially erronous anyway)

usage:
    - read the requirements per file and run via ?build=<filename> This may take up to several minutes, depending on the complexity and your machine

todo:
    - expects parsed dbcs in DB named "dbc" and world-DB to be named "world". Needs to be configurable
    - no error handling. If it fails, it fails badly.
    - pets: locations are inaccurate (see comment in file)
    - itemsets: the fragmented data in itemsets.dbc has to be fixed manually before this script yields propper results (see comment in file)
