* automatic CONVERSIONS -> PROPS navigation

In the Behaviours section, we'll navigate from Goal Conversions > Properties,
when a goal filter is applied by clicking on an entry in the Goal Conversions
list. This navigation does not happen for pageview goals or special goals (e.g.
'Outbound Link: Click', 'File Download', etc.)

The Behaviours component will remember that the navigation happened in order
to return the user to the previous view when the goal filter is removed.

* ability to store prop_keys per goal in localStorage

* pass the onclick handler to the Details view too

This makes sure that when a  listItem is clicked in the Details view,
the same behaviour (such as changing the Locations tab from 'Countries'
to 'Regions') is called.

* bugfix - always escape pipes when applying goal/prop filters

* disable propkey selection when prop filter applied

* make the propkey selector take up all the width
