Merge - devGuide - 02-plugins-sdk - fix lists

Russ,
I merged in changes from plugins sdk, ide, and maven chapter files. I mostly made list related formatting changes. There are a few places where I used the wordsmithing. For example, I took out the eclipse links per Rich's commits ... makes things more maintainable. These changes may have only been on the 6.1.x branch where I started making the list related changes.

Anyway, if you see something you have a question about or disagree with a phrasing, feel free to change it.

Thanks,
Jim
