Pony ORM Release 0.6

Merge branch 'master' into orm

Pony ORM Release Candidate 0.6rc2

Pony ORM Release Candidate 0.6rc1

http://blog.ponyorm.com/2014/10/08/pony-orm-0-6-release-candidate-1

# New features:

* Python 3 support
* pymysql adapter support for MySQL databases

# Backward incompatible changes

Now Pony treats both `str`` and `unicode`` attribute types as they are unicode strings in both Python 2 and 3. So, the attribute declaration `attr = Required(str)` is equal to `attr = Required(unicode)` in Python 2 and 3. The same thing is with `LongStr` and `LongUnicode` - both of them are represented as unicode strings now.

For the sake of backward compatibility Pony adds `unicode` as an alias to `str` and `buffer` as an alias to `bytes` in Python 3.

# Other changes and bug fixes

* Fixes ponyorm#74: Wrong FK column type when using sql_type on foreign ID column
* Fixes ponyorm#75: MappingError for self-referenced entities in a many-to-many relationship
* Fixes ponyorm#80: “Entity NoneType does not belong to database” when using to_dict
