Although the bug report here wasn't exactly clear about what exactly was wrong,
it soon became apparent that the UI stuff here was in need of some love.
Changes:
* Ported over missing tooltips from 2.49 (i.e. most of them)
* Fixed a few incorrect tooltips (mostly the subdivision length settings)
* Made the autonaming and number/side settings slightly clearer - number/side
are used to replace placeholders in the names of template bones (&N and &S
respectively) when autonaming is disabled. When it is enabled, these values are
determined automatically.
