Updates (Batch Encoder GUI Fix)

• I stripped the un-needed brackets ({}) off of the file input for drag and drop. This didn't change the function of the app however it does make it look nicer when displaying the save file/view commands
• Show commands "FFMPEG" location will now update correctly based off where you choose in the "Set FFMPEG location"

• NOTE: This was fully functional internally, however it did not correctly display on the show commands window
