Title: extended movie writer to optionally allow the AVAssetWriter fileType &...

...AVAssetWriterInput outputSettings dictionary to be specified on init

- movie writer can still be setup & used as before, & the default fileType & outputSettings are used in that case (as set in initializeMovie)
- an extended init method was added that can override these settings

TODO: if supplying a custom outputSettings dictionary, you currently need to manually specify the AVVideoCodecKey, AVVideoWidthKey & AVVideoHeightKey values. Could look to auto set these if their left empty (or is there any use case were you might want to leave them empty?)
