Robust configuration management.

Fixed

• Wait until a configuration is completely written and validated (non-blank script.txt) before saving over the original.
  • Consolidate path, saving, and loading code.
• Handle all situations regarding missing, blank, or invalid startup.ini (regarding selecting profiles).
• Manage "non-dated" files (TrueCrypt and VeraCrypt image files where timestamp doesn't change when files inside are modified--See #16)
  • Requires hc or tc extension!
• Full Changelog: 1.0.2...24.6.13
