Fixed:
- Upload max file size (really post max size) error not showing when updating a page (it would just fail and redirect to the main top-level pages).
- Upload max file size not showing for upload fields that weren't images.

Class comments.
Fixed use of eval in favor of $.parseJSON

Fixed JPG images that were rotated failing to upload.
Added a new BigTreePasswordInput class to replace default password input fields on the add/edit user page due to all major browsers moving to ignore autocomplete="off" causing saved logins to auto populate in the email / password field on those pages.
Fixed module classes add/update methods not converting internal page links.
Fixed the add method and update methods only supporting array values in some cases instead of all.
Hopefully fixed tooltips and menus in callout popup getting stuck when switching callouts.
Let's try the last one again...
Need both... :|
