[FEAT/BUG] Automatically convert arguments of path/query to string

[icaine]

• Bug part: I was trying to do something like .add_path(['user', 123]) and it didn't raise an exception during the execution of the method but only when i called .get, which is imho late.

• Feature request: Everything should be converted to str automatically (not raising error) or at least usual types like int, float. I think it should be user's responsibility to provide desired str output and everyone knows that resulting url is always str.

Nice catch! Will get to fixin'.

For now, I've only made it raise an AttributeError if it receives a list and it has something other than str inside.

I'm still thinking of a good way to implement the automatic conversion part.

In my wrapper function that i am using to bypass some problems that i encoutered (and reported) i use something as simple as [str(p) for p in path_parts].
