* upstep bun and sqlite versions * allow specific columns to be updated in the db * only update necessary columns for user * bit tidier * only update necessary fields of media_attachment * only update relevant instance fields * update tests * update only specific account columns * use bool pointers on gtsmodels includes attachment, status, account, user * update columns more selectively * test all default fields on new account insert * updating remaining bools on gtsmodels * initialize pointer fields when extracting AP emoji * copy bools properly * add copyBoolPtr convenience function + test it * initialize false bool ptrs a bit more neatly
