$variable naming & comments

[SteveTheTechie]

Mostly a variable re-naming and commenting update.

1. Updated version number to 3.0.0 in code heading

2. Updated jQuery version dependency to 1.7+ due to deprecation of $().delegate & $().bind(), and use of $().on() instead

3. Detailed comments for each option to explain the permitted value types and the intended use of the option.

4. Switch default for selectedText option to be # of # selected to ensure that developers know that this form is supported.

5. Follow the popular convention of prefixing variable names of jQuery objects with a dollar sign for more clarity.

6. Use local variables for properties fetched more than once.

7. Ditch use of $().bind() in favor of $().on(), as bind is deprecated.

Unit tests have been updated.

I guess GitHub will not let me do a squash PR if I am bringing over a feature branch I created. ?

Sorry, I intended to do a squash commit. Thank you for your generous patience w/ me.

To squash it and have it reflected on the PR you would rebase and then force push the branch. The changes would be reflected in the PR automatically.

Thanks. I wish I had your skill with Git and GitHub. I have done several online tutorials and read a lot about Git, but I still struggle w/ it.

I've just been using it for a few years. Have you used any version control software other than git, like SVN?

[SteveTheTechie]

As I am a hobbiest developer (just do this in my spare time), I just do not have the experience with it. I have done a little bit with the check out/check in type of version control systems in the past (I think this is the SVN model).... most would be considered outdated/obsolete by today's standards.
