Add emacs backup files and egg info directory to .gitignore
Add user detail view

Users in the dashboard link to user detail view for each user. All
page views are aggregated into one large table.
Platform and geo data in user details view
Added property 'platform' to model Visitor.

This property takes the user agent string and extracts basic platform
version, e.g. Browser, OS, device. Presents the user agent string more
human-readable. The user_details view uses this property.
Started work on user visits view

This work isn't finished yet. Will probably remove user details
view. User visits view uses class-based generic views. Will also add
Pageviews view for a particular visit.
'User Visits' and 'Page Views' views added
Remove user detail view
Removed deprecation warning
