[#316,timeline][m]: timeline now handles BC dates and has a switch to support non US dates dd/dd/dddd - fixes #316.

* upgrade timeine view to latest TimelineJS (note vendor code went in in last commit as needed to patch in this one)
  * Minor fix to TimelineJS timeline.js code (actual bug I think)
* BC (-ve years) support is provided by latest TimelineJS (raw vendor code in last commit)
* Strip out use of momentjs and just use timelinejs date parsing (various changes and tests around this)
* state option nonUSDates: true to parse dd/mm/yyyy properly
