Finish refactoring and clean all the mess.

[Kaik]

Around 90-95% of Dizkus is "refactored" it should work... Next 2 maybe 3 weeks I'm busy so work on Dizkus will slow down.
Things to do:

• Installation test's
• Upgrade test's and fixes DizkusModulInstaller Upgrade 3.1 - 4.0 - dizkus_users - wrong column name #298 Upgrade fails  #308
• UserController - finish refactoring and test's
• AdminController - test's
• Review Forum, Topic and Post Controllers - there are unfinished actions (split topic, post edit etc..)
• SynchronisationHelper - posters - to fix.
• NotificationsHelepr - review and re implement notyfications as it was not touched
• CronHelper - not touched
• RankHelper - some functions regarding image manipulation may not work.
• SearchHelper not touched just moved from Api
• EventListener - check if it works properly as it was not touched
• All Managers need to be reviewed and cleaned, they work but it is mess
• FormHanlders - need to be refactored to symfony 3.0 field class names - easy
