BURs: clean up parsing and error handling.

Browse Source 
* Don't raise exceptions when a BUR is invalid. Instead, use Rails
  validations to return errors. Fixes invalid BURs potentially raising
  exceptions in views. Also makes it so that each error in a BUR is
  reported, not just the first one.

* Revalidate the BUR whenever the script is edited, not just when the
  BUR is created. Ensures the BUR can't be broken by editing. Fixes a bug
  where forum threads could be broken by someone editing a BUR and
  breaking the syntax, thereby causing the BUR to raise an unparseable
  script error when the forum thread was viewed.

* Validate that removed aliases and implication actually exist.

* Validate that the tag actually exists when changing a tag's category.

* Combine bulk update request processor unit tests with main bulk update
  request unit tests.
