multi-template file and renderResponse support

[vivekvrao]

Added a couple of function to simplify using the module.

1. multiple templates can be loaded from one file using loadTemplates

SSR.loadTemplates(Assets.getText('templates.html') );

<!-- file: private/templates.html -->
<template name="mytemplate">
      Hello {{username}}, <br>
      Now time is: {{time}}
</template>
<template name="another">...</template>

2. Utility function for serving pages - renders the template with given data - and serves over http response with support for Head sections and metadata

SSR.renderResponse( templateName, data, responseStream, metadata) 

Router.route('/hello', function(){
    SSR.renderResponse( "mytemplate", { username: "me", time: "now" }, this.response, {title: "mypage", keywords:"test,ssr" } );
});

Hi there, does this mod allow use to do sub-template inclusion, like {{>subtemplate parameter="param1"}}?

SSR.loadTemplates(Assets.getText('templates.html') );

<!-- file: private/templates.html -->
<template name="mytemplate">
      Hello {{username}}, <br>
      Now time is: {{time}}
      {{>subtemplate parameter="param1"}}
</template>

<template name="subtemplate">
</template>

We could use this in lookback:meteor-emails lookback/meteor-emails#88
