Fix removeColumnQuery for mssql dialect

Fix Postgres showIndex not returning functional indices

* As per the syntax tree at:

  https://msdn.microsoft.com/en-gb/library/ms190273.aspx

  the correct syntax for removing a column is:
    ALTER TABLE users DROP COLUMN name;
  instead of:
    ALTER TABLE users DROP name;
  which is instead the syntax to drop the 'name' constraint.

Pass through connection mode options to sqlite

Support custom field names in json queries

defined custom field names

JSON: Cast key when using the equality operator

- Perform file existence checks using `fs.open` for older versions of node.

- Default to SQLite's default of OPEN_READWRITE | OPEN_CREATE
- Added tests to verify access errors when connection opened with a more limiting mode

Fixed `operator does not exist` exception when using queries like:
```js
{
  'data.age': 4
}
```
