adding the why field to event
First version of event detail page

Still need to work on the time left till the event, displaying links,
popular vote and comments.
Merge branch 'master' of github.com:hasadna/Open-Knesset
Return current party agenda values
Current mks only for agenda view
Fix #3858 - annotations popover to the right
fix methods returning unicode representation of committee / committee meetings

mostly to fix the display of plenum in annotated texts
Merge branch 'master' of https://github.com/hasadna/Open-Knesset
highlight plenum in the nav bar for the plenum all_meetings page
delete duplicat meetings - apparently the knesset sometimes provides duplicate meeting files with different file names

I identify duplicate meetings using same date + same number of protocol parts
Better optimize committeemeeting Api queryset and result size
Make member name clickable as well
Remove numbering from css
Ipad and mobile fixes

Don't show mks popovers on smaller resolutions, make mk image links usable on
mobile devices
Better handling of mk card

- Shadow
- Delay on apperance
- Center
- display: none on smaller screens
Lazy load of large mk images
Profile annotation links less confusing
TagResource honors list_fields
list_fields for CommitteeResource
absolute_url in TagResource
