Probe start-up time improvements.

Here are some candidates to optimize:

 - NCNumericManager ~ 700ms - Review the initial loading of cached values and reduce the amount of string concatenation/rewriting/trimming operations
 - NCNlpCoreManager ~ 1500ms - Try not to use runtimeMirror of Scala reflections as it takes most of the initialization time
 - NCDictionaryManager ~ 700ms - Review loading of dictionaries from files
