remove node-sql and query generation syntactic sugar

This is an incomplete feature that seems to be unused by the user
base. Furthermore, it does not support incoming dialects (notably
MSSQL), and thus has been slated for removal for the 2.0 release

Fix allowNull in combination with primaryKey

…ield prop after create, fixes #2468

Fix increment and decrement usage with schemata

…/sequelize into vpontis-associating-sections-when-deletions

…result in a promise chain

add ability to test for dialect transaction support

…nd attributes as fields

Transaction support is currently very limited in the MSSQL dialect,
this allows us to conditionally skip transaction related tests for
a given dialect. I imagine it's also a nice feature to have when
adding a new dialect, so you don't have to solve all one thousand
errors at the same time

This commit adds a test that checks allowNull in combination with
primaryKey.

Update dependencies

This commit updates bluebird, sql and validator. The latter one is
reported to be vulnerable:

Upsert

…verted properly to SQL. Closes #2077
