v4.0 (#51)

## Release v4.0
Release v4.0 is a major code overhaul that introduces the following new features and improvements:

### New features
- **Ignore list**:  shortens time required to find new files on script execution by excluding files the script has already successfully processed
- **Clone audio to stereo track**: Addresses #42 - when enabled, will create a stereo copy of any non-stereo audio tracks for each file for playback on stereo systems (while retaining the original audio track)
- **Metadata title**: Sets the file's metadata title to the filename (helps with Plex matching) [thanks to   @djgrijalva]
- **User-defined failover threshold**: User can now define the failover threshold to any desired percentage (Addresses #38) 
- **Failed encoding reporting**: List files that failed to encode (even after failover) in the log
- **Corrupt file reporting**: List corrupt files in the log (files with either corrupt video or audio codecs)

### Improvements
- **Configuration**: Configuration is now set by the user in a plain text file
- **Code enhancement**: Code is now modular, increasing readability and ease of adding new features
- **Portability**: Pulling the latest version of the code will not overwrite or otherwise change any user settings in the config file
- **Validation**: All user-defined settings in the config file are validated prior to the script executing. Any errors will cause the script to log a relevant message and exit.
- **Timekeeping**: Fixed various issues with timekeeping in the script, resulting in more accurate statistics
- **Best practices**: Various changes to conform to Powershell best practices

 # conv2mp4-ps
-Powershell script that recursively searches through a user-defined file path (*or paths*) and convert all videos of user-specified file types to **MP4** with **H264** video and **AAC** audio as needed using ffmpeg. If a conversion failure is detected, the script re-encodes the file with HandbrakeCLI. Upon successful encoding, Plex libraries are (optionally) refreshed and source file is deleted. The purpose of this script is to reduce the amount of transcoding CPU load on a Plex, Emby, or Kodi server and increase video compatibility across platforms.

+**Features**
+- **Full automation**: Set as a [scheduled task](/docs/SCHEDULED_TASK.md), and convert/encode your files while you do something more interesting.
+- **Detailed logging**: Allows easy tracking of what files are in the queue, overall queue progress, individual and cumulative file size gains and reductions, as well as total hours of video converted, how long it took to convert them, and the average encode speed.
+- **Plex integration**: Refreshes Plex libraries upon completion of each item in the queue.
+- **Garbage collection**: Allows user-specified file types to be deleted during each execution, keeping non-media files such as .nfo or thumbs.db from accumulating.
