Title: Improve the MSSQL database driver

Changes include:

- Method/property visibility declarations
- Added random ordering support
- Changed `CI_DB_mssql_forge` and `CI_DB_mssql_utility` to use `protect_identifiers()`, instead of `_protect_identifiers()` at the latter is supposed to be a protected/private method and is currently declared as public because of such uses
- Minor speed improvements
- General clean up
