* ./src/misc/modules.c: added the "any" and "none" keywords to the module

    selection string. "any" matches any module, and "none" always fails.

    You can for instance use "--vout none" to disable video output, or
    "--intf gtk,any" to use the gtk interface or any other one if gtk isn't
    available. Hope it's clear :)
