Add Exclude Files to File Watcher & Switch to Regex for Exclude Logs

[aphralG]

Proposed changes

• Added Exclude File to FileWacther
  • Events that trigger from files that match either an exact file path or regex pattern will be ignored
  • Switched from filepath.Walk to filepath.WalkDir which is more efficient
  • Stopped adding a watcher to each file, a watcher is only added to directories
  • Default is ^.*(\\.log|.swx|~|.swp)$ which excludes all files ending with .log, .swx, .swp or ~
• Exclude Logs now uses regex or a full file path instead of using shell pattern matching
  • example: ^/var/log/nginx/*.log now needs to be ^/var/log/nginx/.*.log$ to exclude all log files from /var/log/nginx
