`guided_tour.rs` in master does not compile with rlua 0.15.3

Since 4e4d65e guided_tour.rs uses context() which is not available in rlua 0.15.3:

error[E0599]: no method named `context` found for type `rlua::lua::Lua` in the current scope 

As a newcomer to rlua this puzzled me a bit.

I see the following options for improvement:

• release a rlua > 0.15.3 which works for the guided_tour.rs in master
• point out the current situation in the README.md
• point to the last revision of guided_tour.rs working with rlua 0.15.3

Hopefully I will release a 0.16 very soon which will fix this

My (amateurish) understanding is that you can just omit the context calls and use the Lua object directly.

Fingers crossed for 0.16 :)

Fingers crossed for 0.16 :)

I promise I'm working on it now, I'm going to merge #108 and try to merge #95 in some form, then 0.16 will be released :)

This is now fixed (0.16 is released 🎉), but there's still the general problem of the examples folder being mismatched in some way with github / external dependencies. Leaving #91 open for both of these issues.

Nice thank you.
