0.0.115

• Fix a couple crashes that would occur due to insufficient object lifetimes
• Improve level of insight from debug logs, now tracking the Swift line where a freed object was originally created
• Improve concurrency handling for Swift instance caches for trait implementations
• Remove an additional 5 memory leaks. (If this releases introduces new crashes, however, we may end up needing to bring them back. They weren't particularly severe in the first place.)
