New define: PLATFORM_COMPILER_HAS_DEFAULT_FUNCTION_TEMPLATE_ARGUMENTS, indicating whether function templates can have default template args or whether workarounds are needed. This is effectively a global version of ENABLE_TFUNCTIONREF_WORKAROUND from TFunction. Only needed for VS 2012, once we drop that we can remove this.
Now constructs from T* instead of (templated) U*. It cast to a T* anyway, so would have failed to compile with anything that couldn't already bind to a T* arg, so the template was pointless.
As a result no constructor from TYPE_OF_NULL is needed (calls the T* constructor with NULL), so it has been removed. nullptr also now works!
Comparison operators have been made symmetrical (TLazyObjectPtr can now be the right-hand argument as well) and comparisons with nullptr now compile
Implicit upcasting is now enabled in the constructor and assignment, so "TLazyObjectPtr<Base> mybaselazyptr = TLazyObjectPtr<Derived>()" now works, as does passing a TLazyObjectPtr<Derived> to a function that expects a TLazyObjectPtr<Base>. As this is always safe, this works even if the object isn't currently loaded!
The constructor from a TWeakObjectPtr has been removed because it didn't even compile

Includes following engine changes:
Getting display metrics only once at construct time when using SSafeZone. GetDisplayMetrics is expensive in Windows so it is impractical to call it every frame.
- Some AI API improvements, mostly switchig pointer function parameters to references.
- minor refactor of UCrowdFollowingComponent's queryinf functions:
- IsCrowd*Enabled functions refactored to IsCrowd*Active
- implemented IsCrowd*Enabled that return acrual values of relevant properties
- Added a function to CrowdManager to query for location of agents neighbouring given agent
Added support for PS4 touchpad-based cursor
You can now choose to skip synchronously scanning for asset data in object libraries and just use the data that is currently in the asset registry. The data will be refereshed automatically later once the global scan completes. The only applies to non-commandlet editor instances.
