TagCloud should optionally be case-insensitive

[Jeff Hammel]

Because of the use of sorted intagsplugin/trunk/tractags/macros.py#L47​, upper-case items precede lower-case items. These should optionally be intermingled. Patch attached.

From #5347 (which is a duplicate of this), reported by: k0s

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.

Seems like it aims at a similar thing as #4200 or even might get obsoleted by it.

However the configuration option to retain old/default behavior should definitely be considered. Thanks for contributing your changes.
