Dota 2 update for June 14, 2017

Added new hero health bars which display hero level. The emphasized thousands health bar ticks have been reactivated.
Fixed a number of bugs with spectating Siltbreaker games.
Fixed a bug with combining items which could cause items to incorrectly be placed into the backpack.

Rumor has it:

Panorama updates for the refreshed health bars with levels (oh, by the way, levels? literally League of Legends): View Dota2 game tracking changes 8634c769cb for this build
