Add basic support for key prefixing

* Some variable standardization to help me and others be able to read the code better.
* Moved output whitespace to a variable so we can tweak it when/if necessary.
* Bug fix on extra white space added for imperitaves. e.g. no data values.
* Define a few missing variables... would be nice if V8 would warn on this
* Enable toggling of the `true` on `uniques`... e.g. if you toggle it to false it will be ignored.

**TODO**:
1. Find the code for collaboration and...
2. Break `@collaborator` and `@author` ... but fix it too. ;)
3. Prefix `@collaborator` and `@author` with `oujs`... thus making `@oujs:author` and `@oujs:collaborator`
Readd `@author`... need this for testing

Applies to #226 and #208
Swap out `@collaborator` and `@author` for prefixed keys

* Needs total verification that I haven't missed something.
* I do have some redundant tests in for `meta.oujs` existence but I'll remove those on demand.
* Hopefully this is everything needed.

Applies to #226 and #208
Remove some duplicated `meta.oujs` checks... the remaining one should probably stay in there since it's an `||`

Applies to #226 via #208
Change add/scripts page to reflect these changes.

* Removed text `Only the author may edit.` from `@author`... that doesn't make sense to me... but did put in `Required to enable Collaboration` change.

Applies to #226 via #208
Missed an instruction on the page to use prefix

I could have swore that this was committed a few days ago... No idea how this crept back in... SF changed their wiki store... correcting links to the new path and removing from specifics

Applies to the esrs.
Missed identifier change

* Mentioned in https://github.com/OpenUserJs/OpenUserJS.org/pull/226#discussion_r14328498

Thanks Jerone :)

Merging for sizzle... he can test and deploy but we're lagging behind a bit here.
