Small fix for the amalgamator

[kunitoki]

this:

    StringArray lines;
    lines.addLines (content);
    while (lines[0].trim().isEmpty())
        lines.remove (0);

should read:

    StringArray lines;
    lines.addLines (content);
    while (lines.size() > 0 && lines[0].trim().isEmpty())
        lines.remove (0);

as this could be safe for everyone (not likely you will have a zero sized file, but if you are amalgamating external code like libpng or the like, where empty files could be present…)

Yes, fair point!
