Microsoft CRM 2011 Solution backups with help of Plugins.

     This small plugin can save a lot of time and put things under control. Each time somebody press on Publish All button, it creates a backup of all user solutions (system solution is ignored) and creates a task in the system with attached backups. So you can easily find a right task with right backups of solutions.
