got rid iof $H.

$H is a hash object in prototype which was included in the mojo
framework. No advanced methods of the hash object were used, so I
replaced the hash with a simple object and use that to store key-value
pairs.
converted doInstall, doRemove and doUpdate for packages

This is still incomplete. Need to find a way to reproduce old
communication with assistant. Maybe spawn enyo popup here? Or send
signals?
added "include" function to string object

this is taken from prototype library and used in PackagesModel and some
other files. Where to put that? Or how to best replace it?
changed log output in feeds.js.
some changes to the update status list methods

need to find a proper way to receive the status update signals from the
library part.
