[Fix #116] Set inf-clojure-buffer REPL type on detect

[arichiardi]

Now the code sets the inf-clojure-repl-type buffer local var in the inf-clojure-buffer when a REPL type is detected. This solves the weird errors that were happening when working within the REPL buffer because inf-clojure-repl-type is nil.

• The commits are consistent with our [contribution guidelines][1]
• The new code is not generating bytecode or M-x checkdoc warnings
• You've updated the changelog (if adding/changing user-visible functionality)

This was indeed easy, style can be improved because setq returns the value so everything can be threaded but it looks okay this way too.

Why do we need to set the REPL type in the source buffer? We can always infer this from the REPL buffer for the project.

[arichiardi]

Uhm are there any implications in terms of performance in getting the buffer and from it the value for every operation? Remember this is done on each key press (for completion). If not I can change things, but this patch was definitely easier.

I think also that removing the buffer local would work but I was thinking that at some point we should have more than one repl (per project) so I don't know how it work then.

[arichiardi]

I updated the code and also notice that we have a defvar-local that can be manually set. As long as it is not nil detection will be skipped.

I think you put to wrong changelog entry here.

[arichiardi]

Yep I renamed things and forgot it, will do
