Fixes:
- Console - Comments are now accepted where new command can start, that is, where '/' or ':' characters can be used to start new command

- Files with '.sensitive.' in the filename require 'sensitive' permission to manipulate
- LCD - Reduce CPU usage when displaying static screens
- L2TP - Fixed occasional server lockup
- PPTP - Fixed memory leak
- SSTP - Fixed crashes
