Add tutorial config and initialdata files
Add tutorial document

Add as a module file to make it easier to find and link to
on metacpan.
Check in images

We'll host these on static.bestpractical.com, but check them
in to track them with the extension and make them available
locally for users.
Move getting started docs into primary module file

This will make it much easier to find on metacpan. We can
move it back to docs when it becomes part of RT.

Re-add necessary =encoding line
Trailing "1;" is unnecessary, and shows up in POD
Unwrap incorrectly wrapped link
Trim trailing whitespace
Typo fixes
Simplify wording; also, because on 4.2 and above we recommend Plugin()

Minor wording changes
