James D. Callahan III:
    - Completely re-wrote GetOptions() - only the main options table is generated by hand - all args are generated at runtime. Now all possible chat filter types can be toggled for alerts.
    - In TabAlerts:OnEnable(): Replaced hard-wired event registration (which missed a bunch of events) to be dynamic according to the SavedVariables state.
    - Added all of the filter/event pairs to LISTEN_EVENTS.
    - Use local _G references to InterfaceOptionsFrame and InterfaceOptionsFrame_OpenToCategory()
    - Removed all db defaults that were set to false - they're automatically nil, so tests will work regardless.
    - Call FCF_FlashTab() from local _G reference.
    - Upvalued string and ipairs.
