A character's AddOns file now holds only the rows the character chose, as in 1.12.1, so a character that never chose an addon keeps following what the realm's other characters agree on (`0x51e470`) instead of freezing its inherited values at the first logout.
- Each character has an enable hash and a dirty flag: the loader `0x51ebe0` fills the hash from the file, clean; the setter `0x51ea20` inserts on a miss and dirties the hash only on a change (`0x51ebab`-`0x51ebbc`); the writer `0x51ef20` writes a dirty character's hash, a line per entry, and nothing else (`0x51ef59`).
- Logout and exit (`0x490c88`) and the character-select AddOns screen's Okay (`SaveAddOns` `0x46d990`) both write through it, so a session that toggles nothing writes nothing, and no `Blizzard_*` rows appear.
- `ResetDisabledAddOns` restores the hash as loaded, clean (`0x48e830`).
- On the AddOns screen a character with no row now follows another character's toggle at once, as `AddonList_Update` re-reads each column after every `EnableAddOn`.
