Release of Centreon Engine 1.3.0

This new version implements a key feature, the use of connectors. The main purpose of these daemons (programs that are run in background) is to provide better execution context to the check plugins. For instance:
•    SSH connector: this component is a connection multiplexer. It offers the reduction of open connections and it also makes them persistent
•    Perl connector : this component embeds a Perl interpreter and somewhat enhances the execution performances of plugins written in Perl
The other noticeable features are the following:
•    Replacement of the Qt library by centreon-clib and libxerces (for the XML part)
•    A few fixes

Release of Centreon Broker 2.2.1

This new version enhances overall performances thanks to the implementation of SQL transactions. Basically, the concept of these transactions is to group queries in order to generate less input/output on the server. When transactions are used, the executed queries affect a virtual copy of the database. It is only at the end of this operation that data is actually written in the disk and  made accessible to users. This mechanism highly enhances the input/output situation of the storage device.

The other noticeable features are the following:
•    Non-process of host/service statuses that are too old (next_check < now)
•    New statistics module for retrieving information such as the list of loaded modules, processing speed, connection status, etc…
•    Deactivation of the SIGCHLD signal (less back and forth signals between kernel-space and user-space)
•    Rotation of log files (for limiting storage issues)
•    Possibility to write cbmod logs directly in the Centreon Engine/Nagios logs
•    Possibility to disable log synchronization on the disk (*sync* system calls)
•    Stalled callbacks with Centreon Engine/Nagios (lesser restarting time)
