Added addMMPRules for adding conditional MMP_RULES

Usage:

    # Set conditional libraries
    LIB.MARM = "LIBRARY myarm.lib"
    LIB.WINSCW = "LIBRARY mywinscw.lib"
    LIB.default = "LIBRARY mydefault.lib"

    # Set conditional Epoc Heap Size
    EHZ.WINSCW = "EPOCHEAPSIZE 0x2000 0x2000000"
    EHZ.default = "EPOCHEAPSIZE 0x40000 0x400000"

    # Add the conditional MMP rules
    MYCONDITIONS = MARM WINSCW
    MYVARIABLES = LIB EHZ

    addMMPRules(MYCONDITIONS, MYVARIABLES)

This will generate the following in the mmp file:

    #if defined(MARM)

    LIBRARY myarm.lib

    EPOCHEAPSIZE 0x40000 0x400000

    #elif defined(WINSCW)

    LIBRARY mywinscw.lib

    EPOCHEAPSIZE 0x2000 0x2000000

    #else

    LIBRARY mydefault.lib

    EPOCHEAPSIZE 0x40000 0x400000

    #endif
