GAMEPLAY

UI

 * Added Suggested Item Editor. Access this from the shop, all your new builds will be saved to the cloud.
 * In multiselection, units with active abilities are now sorted ahead of units without active abilities.

 * Improved how bots handle defending a building that's within their base.
 * Fixed bug where bots would accidentally know about invisibile enemy heroes nearby.
 * Reworked how commit-to-attack calculations are done. Bots should be better about evaluating their surrounding threats and in particular should no longer walk by each other like ships in the night.
 * Improved bot last-hitting performance.
 * Fixed item build issue with Earthshaker Bot.
 * Tidehunter will use Ravage more intelligently now (tries harder to hit multiple enemies ).
