Title: Fix for return type of [FMDatabase indexNamesOnTable:]

Thanks for the useful project!

I noticed this method was declared as an `NSArray`

```
/**
* Returns the names of all indexes on a given table.
*/
- (NSArray *)indexNamesOnTable:(NSString *)tableName;
```

but implemented as an `NSSet`

```
- (NSSet *)indexNamesOnTable:(NSString *)tableName
{
FMResultSet * schema = [self getSchema];
NSMutableSet * indexNames = [[NSMutableSet alloc] init];
...
return indexNames;
}
```

I think `NSSet` is the right type.
