TooManyAddons

-- Fixed some issues that surfaced as a consequence of renaming the addon directory and files to modern conventions. Windows and MacOS were case insensitive. LUA was not. Mostly this manifested as TooManyAddons being mysteriously unchecked in the "Always" profiles and any other profiles where it was explicitly set, and was easily remedied by re-checking it. But inconvenient.  Added some code to preserve existing settings by translating them into the corrected internal representation on the fly.

-- Cleanup: Remove unused internal references to a separate globals frame that was never actually used after globals and locals were combined into the same frame with a Global / Local button
