* - Re-added timer to check on mp3 file conversions and implemented levenshtein to validate it's a file that needs to be converted
-  Added right-click menu on datagrid to clear it out
- Added right-click menu item to restart failed downloads/conversion
- Added right-click menu item to open data file directory
- Set default state to "paused" so user can make adjustments/fixes before starting process
