4.0.3.1 (Lisias) for KSP >= 1.3.1

• Updating code to the latest KSPe API
  • Getting rid of deprecated warnings
• Getting rid of the overcomplicated logging code
  • Relying on KSPe to that
  • Logging into a file will be implemented later on KSPe itself. Place holders were kept.
• Merging upstream updates:
  • Improvements on thread safety
  • Small improvements on performance (regex caching and preserving config cache when just whitespaces were changed)
  • Better handling of Escape Chars, SHAs and URLs
  • Some code cleaning and better test cases
