Include open sourced places

[Kampfkarren]

In production places often do wacky stuff, and are a good baseline for catching issues. rbxlx-to-rojo, for example, uses the Line Runner template from Roblox as a testing file. Would be a good idea to include uncopylocked places in the test files, though it might increase file size a bit.

Coming back around to expanding this repository as part of the rbx_xml upgrade to rbx_dom_weak 2.0. I think using templates is a great idea, but I'm also worried about file size.
