Priit Laes:

When trying to automap legacy database which has some issues with foreign key naming I ran into following issue.

Having following two tables, it barfs because of naming conflict between column `table_b.table_a` and relationship `table_b->table_a`
```
#!python

table_a:
id

table_b:
id
table_a (foreign key to table_a.id)
```

Error message nicely tells me to `To resolve this, map the column to the class under a different name in the 'properties' dictionary.`, but automap part of documentation doesn't mention much about this case.

I have tried to override the class generation using following constructs, but still fail with error above:


```
#!python

class Table_B(Base):
    __tablename__ = 'table_b'
    table_a = Column(ForeignKey('table_a.id'))
```
