Issue #6 - Changed 'use' to override the default plugins

[ianbrandt]

The 'use' parameter now overrides the default fontmin plugins instead of augmenting them, per Issue #6.

This pull request totally works. Thanks!

To anybody trying to figure out how to use it:

gulp.task('subset', function () {
    var gulpFontmin = require('gulp-fontmin');
    var Fontmin = require('fontmin');
    return gulp.src('path/to/font.ttf')
        .pipe(gulpFontmin({
            use: [Fontmin.glyph({
                text: '天地玄黄 宇宙洪荒'
            })]
        }))
        .pipe(gulp.dest('destination/to/subset/fonts/'));
});

@junmer, This has been working without issue for me for some time, and also has a confirmation from @nikoladev. I'd love to move off "gulp-fontmin": "ianbrandt/gulp-fontmin.git#issue-6" to a release version. Any chance for a merge?

Nope, fontmin is dead

@junmer, I don't mean to bother you, but could you please take a brief look at merging this pull request?

Excellent idea for the default list of fontmin plugins to take effect only when the user hasn't provided their own list. However, it would also make sense to still let the opts.chineseOnly option be applied regardless of that.

It seems like opts.ChineseOnly should take effect regardless of whether custom opts.use were passed. I would consider taking this part back out of this conditional block.
