support other script loaders

[zaaksam]

I like to use typescript, so my webpack config like this:

resolve: {
    extensions: ['.ts', '.js', '.vue']
},
module: {
    rules: [
        {
            test: /\.ts$/,
            loader: 'ts-loader', 
            exclude: /node_modules/,
            options: {
                appendTsSuffixTo: [/\.vue$/]
            }
        },
        {
            test: /\.vue$/,
            loader: 'weex-loader'
        }
    ]
},
externals: {
    vue: 'Vue'
},
plugins: [
    new webpack.BannerPlugin({
        banner: '// { "framework": "Vue" } \n',
        raw: true,
        exclude: 'Vue'
    })
]

@zaaksam You could not just add '!' + lang + '-loader' to .the loader, because some differences lang scripts may use the same loader, like sass and scss (the script is the same). You can refer to this pr to make some changes.Thanks
