UETOOL-332 - Collections 2.0
UETOOL-369 - Want nested collections with collapsing
We now have version 2 collections which maintain a persistent GUID for each collection. Existing collections will be lazily updated to this version when they need to be re-saved.
This GUID is used by child collections to keep track their parents, and the collections view (as well as the quick asset management) now show a tree of collections. Collections in the main collection view tree can be re-parented via drag and drop.
Performing Content Browser searches against a given collection will also test to see if an object exists in child collections, and the asset view will now show you folder entries for child collections when viewing a parent (if folders are enabled in your Content Browser view settings).

UE-17109 - Collections cannot be created when using SVN as your SCC provider
The collection was trying to add itself to source control before the file had been created. Perforce allows this, but SVN and Git do not.
Additionally, SVN was trying to recursively commit any added parent folders when committing a file within those folders (required to avoid the commit operation failing), however that was failing to get the current SVN status of anything but the most immediate parent folder, causing the recusive check to fail.

UETOOL-332 - Collections 2.0
This avoids the need to repeat the module name throughout the code (and potentially performing an FName look up each time).

The collections manager now stores a reverse look-up from the objects within its collections, to the collections that contain that object. This avoids the GetCollectionsContainingObject and GetCollectionsContainingObjects functions having to iterate the collections for each object queried, which can be a large win for large sets of objects.
This also adds some functions needed for the quick asset management feature.

UETOOL-332 - Collections 2.0
Removed some duplicated data from FCollection (AssetList and AssetSet) as they had to be manually kept in sync. Only AssetSet exists now, and is converted into an array and sorted before being written to disk (to keep the order consistent for diffing). DiskAssetList has also been converted into a set (now DiskAssetSet) as this is only ever used for lookup queries.
All manually memory management has been removed from FCollectionManager, and the array of maps to collections has been converted into a single map using FCollectionNameType as its key. This simplifies collection lookup code in most cases, and removes the need to manually track the total number of collections outside of the map (NumCollections has now been removed).
Renamed ICollectionManager::GetCollectionsContainingAsset to ICollectionManager::GetCollectionsContainingObject as the function checks for any objects, not just assets.
Renamed FCollection::IsAssetInCollection to FCollection::IsObjectInCollection as the function checks for any objects, not just assets.
Made ICollectionManager::IsCollectionEmpty const.
Replaced all appropriate loop usage with range-based-for, and replaced any NULL with nullptr.
