Title: [DBAL-374] Fix asset identfier quotation

This PR introduces a real solution for the issues discussed in [DBAL-374](http://www.doctrine-project.org/jira/browse/DBAL-374).
It adds the possibility to retrieve quoted column names from Index and ForeignKeyConstraint assets if it is necessary (e.g. column name is a keyword reserved by the platform).
In general column names are wrapped into an abstraction class Identifier which inherits from AbstractAsset inside Index and ForeignKeyConstraint. This allows to get a quoted representation of each column name via the AbstractAsset::getQuotedName.
All platforms are updated to make use of the new functionality.
