        Updated all files in the help/C/dialogs dir. This is
        a first alpha glimpse of the help system. Please give
        me feedback of the content. However since it's in alpha
        stage it means that there is spell, grammatical, etc errors.
        There is may also be pure errors which I hope "you" will
        report to either olof@gimp.org or karin@gimp.org. Please
        don't report spell, grammatical, etc error at this stage in dev.

        If you have any plans to commit to the help system please write
        to olof@gimp.org. (This is mandatory not a please ;-).
