jMessage, manage messages in session and display them in templates

[bballizlife]

Here is a patch for the jMessage class and the jTpl plugin {jmessage}.

jMessage API is :

• jMessage::add($msg, $type);
• jMessage::clear($type);
• jMessage::clearAll();
• jMessage::get($type);
• jMessage::getAll();

How to use the jtpl plugin :

{jmessage}  // display all messages
{jmessage 'error'}  // display only messages that have the 'error' type
