1.6.1 - Bug fixes

What's new

• Cleaner history window
  • Shows timestamp of each save-state
• Split threading options into two categories (IO + Logic)
  • Defaults are higher for both than previous default of 1 (tested on large input, seems about optimal on my 8-core machine)

What's fixed

• Various NPE's in the history window
• More accurate renaming of method hierarchies
• More accurate renaming of classes with inner-classes
• Renaming a class causing a NPE while updating the FileTree model
• Renaming a class and putting it in a directory that does not exist causing a hard-crash
• Renaming a class leaves artifacts visible in searches
• Renaming a class leaves ghost references due to not resetting cache after updating renamed references
• Infinite loop caused by logging calls & JavaFX integration
  • Ironically, only occurs when auto-updating. So this update will cause people some problems ¯\_(ツ)_/¯
