v1.8.0

Features:

• resourcesInitiallyExpanded set to false for collapsing by default (#40)
• performance gains with positioning/sizing (#277, #320) thx @MartijnWelker

Bugfixes:

• updateEvent makes events disappear (#350)
• addResource scrollTo param broken (#335)
• filterResourcesWithEvents considers current view's range (#334)

Incompatibilities:

• Vertical resource view (agenda or basic), when waiting to receive asynchronous
  event sources, previously would render generic date columns as placeholders.
  Now, empty rectangles will simply be rendered.
