Use string for servers like PECL GearmanClient::addServers()

Move classes into Gearman folder (due to collisions w/Minion Tasks folder)
Remove netbeans files and make/build
Automate the compilation of available Gearman tasks

Remove the need to add the Gearman tasks in the config file
Set a Worker function timeout globally in the config
Allow the overwrite of this timeout in each Task
