Add MP.Get

[WiserTixx]

Adds MP.Get(ConfigID) to the lua api to get the current server settings.

lua> print(MP.Get(MP.Settings.Name]))
[LUA] BeamMP Server
lua> MP.Set(MP.Settings.Name, 'Hello World')
[INFO] Set `Name` to Hello World
lua> print(MP.Get(MP.Settings.Name))
[LUA] Hello World

Closes #146

Nice, thank you. An overhaul is in order though, this entire interface of Set and Get is so godawful.

Also, instead of MP.Set(MP.Settings['Name'], 'Hello World'), prefer MP.Set(MP.Settings.Name, 'Hello World').

One style thing, otherwise looks good :) Thanks very much
