* Add [brackets] around mdb-query table names
* Allow column and table names to be in brackets
Column and table names can have whitespace in them. The traditional way
to indicate that is with bracket characters, like so:
```sql
SELECT [column name] FROM [table name]
```
This change updates the parser to allow bracket format -- similar to
double-quoted format -- in all NAME contexts, i.e., column names, table
names, and database names.
