Liferay IDE updates and IDE tutorials

Hi Rich,

This pull request has a few different things in it. I usually try to keep dev guide and dev site things separate, but these changes came to me like this and it's too difficult to divide them now. But they've been QA'd and I've reviewed them and wordsmithed them following your latest notes. 

Here are the associated tickets ...
