Full workaround for old libxml bug.
Add an auto flush function while reaching action=default or action=history.
It will flush all read items older than the specified number of days in
the preferences

Try to refactoring old libxml support (but now it's not supported officially)
added a Star System : starred items will be shown on the Starred Tab
Starred item will not be deleted by auto flush
Added nocontent feature to avoid a to big database
Update gitignore
improve navigation with starred/unstarred  items
improved starred/unstarred function, code refactoring using a mode
session var ('default', 'starred', 'history')
Merge branch 'nocontent' of git://github.com/doubleface/miniflux
