Enums Are Gone

[Max Kanat-Alexander]

	Enums are now gone from Bugzilla. Thanks to everybody who helped! :-)

	For details, see:

	https://bugzilla.mozilla.org/show_bug.cgi?id=17453
	https://bugzilla.mozilla.org/show_bug.cgi?id=281876

	In general, this shouldn't change anything visible to most other
developers. The change was intended to be mostly transparent to existing
code.

	The values now live in tables of their own.
