Fix export functionality

[em0ney]

As per feedback from @jonlachlan we need to fix export functionality and include new examples with working exports

[jonlachlan]

I've worked out some kinks with this throughout the evening, thought I would share them.

• Copied everything from my download amcharts_3.14.0.free/amcharts to /packages/amcharts/amcharts
• Added /packages/amcharts/package.js file

Package.describe({
  name: "amcharts",
  summary: "my free version of amcharts",
  version: "3.14.0"
});

Package.on_use(function (api) {

• Note the {"bare":true}. This is a little-known feature to allow variables to "escape" from the scope of a single file. This is how I like to expose variables so that I can use api.export('myVar');. It's not clear to me whether this is the "best" way though, I haven't heard from the community whether this is good or bad.
• I excluded out "dragIconHBlack.gif" to get rid of an error that I don't understand.
• At this point I was getting an undefined error related to amcharts/plugins/dataloader/lang/en.js, so I added the file amcharts/plugins/dataloader/_define.js with the following code:

if(!AmCharts.translations.dataLoader) {
  AmCharts.translations.dataLoader = {};
}

I don't like to add files within my packages, so I can drop in new versions easily, but I'm not sure how to get around it in this case...

• Obviously meteor add amcharts
• Finally, in the chart definition, make it so it doesn't autoLoad your libs (they're already loaded via the package...)

// within your chart definition:
... 
 "pathToImages": "/packages/amcharts/lib/images/",
 "export": {
  "enabled": true,
  "libs": {
   "autoLoad": false
  }
 }
...

I added "autoLoad":false and added the export plugin .js files to my lib folder manually, fixed it.

This should be fixed since the 3.17.3 release.
