v1.13

• Hotfix for sigh Groovy-related madness, partially reverting memory optimizations from 1.12
• Minor correction to DescribableModel caching lookup
  • Eliminates any risk looking up DescribableModels if different plugins somehow define identical but incompatible Describable classes in the same package and class

v1.12

• Major Optimizations:
  • Cache negative-hits in Symbol lookup (i.e. "no match"), eliminating needless classloading and iteration over classes. 
  • Cache DescribableModels, eliminating classloading associated with creation.  
  • Net result: huge reduction in disk reads, lock contention (classloading), CPU use, and memory garbage generated.
• Minor optimization: reduce memory use and garbage generation (collection pre-sizing and use of Singleton collections)
• JENKINS-46122 Report base class name when symbol couldn't be resolved
