Plugin and Theme discovery ready

Now, pretty much every core feature to handle plugins and themes is ready.

Index json schema is kind of finalized. So we can start extending the index.

Pending features here.

Will tackle this next, in the following order:

• config/options page for UnrePress
• improve documentation at the wiki
• unrepress main site, for plugins and themes search, discovery and submission. Also to provide UnrePress download for everyone else.

After that, the remaining features will follow.

Plugin search and install

UnrePress now supports search and install plugins from the index, as well as updating themes and plugins from the index, and updating the WordPress core from the index.

ToDo: search and install themes from the index.

Added blocking of that ecommerce

Added blocking of that ecommerce domain.

Reason: #11 (reply in thread)

Core update fallback

Core update fallback.

If, for some reason, UnrePress index can't be loaded or core package can't be downloaded from github, then wp.org repository will be used as a fallback.

UnrePress index will always have priority over wp.org

Blocking wp.org disabled by default, to take advantage of this new functionality.

First "public" release

Kind of ready to be used on live sites.

Main missing functionality: search and install plugins or themes from wp-admin, planned.
