Semantic UI update to 2.1.8 (#211)

* Update to Semantic UI 2.1.6

Basically I tried to rebuild the old layout as closely as possible.
It is a bit more mobile friendly but still misses Semantic UIs collapsable menu:
  https://github.com/Semantic-Org/Semantic-UI/issues/157

+ ditch old tablesorter for recommended one
+ use em instead of percentage for status labels in macros

Overview:

+ sort overview by report date per default
+ slightly different colors

Facts:

+ template based approach to even out the columns in facts view
+ don't show empty containers
+ needed an additional variable in context

* get rid of unnecessary semantic src files

* more cleanup

* clean jquery-tablesort directory as well

* drop unused theme files

* remove symlinks in static/{js,css}

* semantic_update

+ bump to semantic 2.1.8
+ minor adjustments
  - default-sort class in tables
  - table type in inventory
  - fixed and wrapped table for reports

* updated screenshots
