#1042 Update database schema automatically

This patch adds database schema management capabilities to ogServer:

  • ogServer now tracks the version of its database schema, if no version

is detected, creates a 'version' table with a single row starting at 0.

  • ogServer can upgrade its database schema to a newer version if

detected. (ogServer ships required SQL commands to do so)

If ogServer is unable to upgrade the schema at startup (if needed be) it
*will not* start.

Defines schema update v1 which upgrades database engine tables of
ogServer database (usually named 'ogAdmBD') from myISAM to innoDB.

  • Property mode set to 100644
