Provide a Plasma "appstore" both desktop and web client

by Francesco Wofford for KDE

== Problem == the ocs -server project it's developing and trying to become Plasma's delivery systembut it lacks a web and desktop client. == Proposed solution== I would like to develop a web client with an easy interface for users to download programs, applications, screensavers, themes etc. giving also the possibility for developers and artists to upload and share their creations.
