Adjusted Terraria protocol to check the "status" property for string "200" rather than integer 200.

I am not sure if the TShock API changed this recently or what, but it returns a string in the current version (4.3.26 for Terraria 1.3.5.3), and comparing it to an integer was incorrectly causing an "Invalid status" error.
