* Create a nascent version of the mod detail page
* Make the slug mandatory for Mod instead of name, and load the name
from the data file
* Make the Feedback view universal on all pages
* Refactor the use of mod pack to have a single global object at the
router level which is shared between pages. Further, make this one
object load itself immediately and have it automatically load any
activated mod version
* Refactor the use of Storage related to mod pack versions into the
router as well.
* Add trace logging back in for events, but allow individual classes
to suppress it (as opposed to actually supressing the events)
* Fix a bug in ModVersion.eachItem where it would suggest so-called
items which are merely registered slugs without associated items
In addition to the new script, this changes the V2 parser to be able
to continue past the first error found so that as many errors as
possible may be displayed.
