Packet 157 - Get User Remote Screenshots

Added Outbound Packet UserScreenshots
* This would give you a list of screenshots given the metadata sent.
* Major thanks to Zelaron just plugging away at it until we cracked the code

Added Screenshot Model
* Written by Zelaron, this Model holds all the relevant data for a screenshot.

* Per usual, this is a frontened-orientated packet, so it has no runtime functionality, but is ready to accept and send data.

Usual MessageType added.
