Pull request for sessionStorage. I'm still a bit of a JS newbie, so I hope they're ok !

Can you update the Readme too?

[udf2457]

Do you want me to close & reopen the PR or will you just pull the updated readme from the fork?

Sorry, don't know my way around the more edge-case corners of github. If there's a better way, let me know.

released in v4.3.0

@udf2457 I've noticed that it only appears to be working when you add lookupsessionStorage to the options.

1. This should probably be lookupSessionStorage (capital S), to match the other prop names.
2. localStorage seems to be working with a default i18nextLng when it is added to the order array and there is no lookupLocalStorage set. We should probably match this behaviour.

[adrai]

I think this is intended, because it is not added by default: https://github.com/i18next/i18next-browser-languageDetector/blob/master/src/index.js#L16
@udf2457 what is your opinion?

[udf2457]

@adrai I'd love to have an opinion, but unfortunately I've moved on to other work and have not spent much time with i18next in recent months.

My guess @adrai is you are probably right in your observation. I'm not exactly a JS guru, so if this relates to the code you pulled in from me, it is quite possible I omited something.

P.S. Whilst I'm here, I agree with @khownz, consistency is good. If you're going to use camel-case, then use it everywhere.

[adrai]

@khownz do you like to submit a PR?

[khownz]

@adrai will do!

1. Change lookupSessionStorage to be camelCased
2. Add a default for lookupSessionStorage
3. Update readme "Detector Options" section

@adrai done: #221

fyi, released in v6.0.0
