Divide async and sync dart version into two separate packages

[goderbauer]

I would like to separate the dart version of pageloader into two separate pub packages: One for sync and the other for the async version (similar to how async and sync webdriver.dart is separate).

Advantages:

• cleaner dependencies (async pageloader doesn't need to depend on sync webdriver)
• easier to deprecate sync pageloader when it is a separate package
• versions for async and sync can increase independently

I would suggest keeping both versions in this github repository. I would just change the directory structure from dart/lib/async and dart/lib/sync to dart/async/lib and dart/sync/lib. The same change would be applied to the other directories (test, etc).

@DrMarcII Any objections?

+1; you can then have a dart/async/pubspec.yaml and a dart/sync/pubspec.yaml.

[goderbauer]

@srawlins That is the idea. There will then be two packages on pub.dartlang.org: pageloader and sync_pageloader. This is similar to how we have webdriver and sync_webdriver as packages.

Great idea! This will make deprecation easier and untangle dependencies.
