Add automatic cdclient migration runner support and setup (#789)
* Add automatic migrations for CDServer Add support to automatically migrate and update CDServers with new migrations. Also adds support to simplify the setup process by simply putting the fdb in the res folder and letting the server convert it to sqlite. This reduces the amount of back and forth when setting up a server. * Remove transaction language * Add DML execution `poggers` Add a way to execute DML commands through the sqlite connection on the server. * Make DML Commands more robust On the off chance the server is shutdown before the whole migration is run, lets just not add it to our "finished list" until the whole file is done. * Update README

* Copy over or create symlinks from `locale.xml` in your client `locale` directory to the `build/locale` directory
|

|
||||
#### Client database
|
||||
* Use `fdb_to_sqlite.py` in lcdr's utilities on `res/cdclient.fdb` in the unpacked client to convert the client database to `cdclient.sqlite`
|
||||
* Move and rename `cdclient.sqlite` into `build/res/CDServer.sqlite`
|
||||
* Run each SQL file in the order at which they appear [here](migrations/cdserver/) on the SQLite database
|
||||
* Move the file `res/cdclient.fdb` from the unpacked client to the `build/res` folder on the server.
|
||||
* The server will automatically copy and convert the file from fdb to sqlite should `CDServer.sqlite` not already exist.
|
||||
* You can also convert the database manually using `fdb_to_sqlite.py` using lcdr's utilities. Just make sure to rename the file to `CDServer.sqlite` instead of `cdclient.sqlite`.
|
||||
* Migrations to the database are automatically run on server start. When migrations are needed to be ran, the server may take a bit longer to start.
