Added sql files for fixtures in database version 4
Function that executes all sql statements in a file, assuming there's one in each line
Added some missing deployment files.
While testing the new initdb script I noticed these files were missing
Added the upgrade.pl script to the list to tidy
Load fixtures into the database when upgrading the database
Initialize the database using DeploymentHandler in initdb.
Added some parameters to the initdb script:
--prepare_init and --init_database to generate the deployment files
and to actually initialize a database
Since now each file is run implicitly in a transaction (rolling back
if there's any error), then I'm removing the explicit transaction
from the job_templates.sql file.
