added units.ini (and campaignUnits.ini), and IniFile got support for load/merging multiple files.

- Rules can now handle map-specific rules changes
    - units.ini replaces {buildings,units,infantry}.txt (or will replace; sidebar still uses them)
    - Added support for loading map-placed units/structures - try scg11eb.ini
        - added FCOM
