Tags should optionally be case insensitive
|Reported by:||k0s||Owned by:||athomas|
currently tags are case-sensitive. while it is desirable to have the ability to use case to denote information (e.g. America vs. plugin), it is undesirable to have different cases be different. That is, Plugin and plugin should be the same tag. I think by default that the first case should be the canonical one. Ideally, a way of managing tags should be implemented that allowed re-casing and canonizing, but a first step would just be treating tags independent of case, at least optionally.
