Added some String Extensions. Fixed some minor typo that were seen.

I've added some small string functions and also I've made small name changes. I thought it would be better to use the plural but of course you may not want to allow the suggestion. ☺️

@JonathanMagnan is this project still active, will be great to get pending PR's through and also, I want to do a PR with a bunch of new extension so wanted to make sure if this is still active.

Hello @Ricky-G ,

We indeed left this project a little bit alone for a while to focus more on other projects (we had a one-point too many requests with all projects we were supporting!)

I'm still using this library in pretty much all personal projects I create so I sure see the value to keep it supported.

To be honest, I would prefer not to touch this library until the end of the summer to focus more to complete everything we have started but that's up to you to provide another PR. I cannot guarantee it will be merged before the end of the summer but we will definitely look at it.

Best Regards,

Jon
