Added set method to AchivementType
Add achivements grid to EditEmployee
Add empty linkDeleteAchivement_Command handler
Add AchivementType enum
Added EmployeeAchivementView class
which is serializable version of EmployeeAchivementInfo

Added some fields to the achievements form
and bind data from them to the gridview
Removed secondary columns from gridview
(need to add a tooltip with leftover information later)
Added achievement description field
Added achievement document URL field
Added new "Work" achievement type 
to describe employee's previous work experience
Implement delete and (partially) edit commands
Refactor item search to use List<T>.Find() method
Added ability to edit selected achievement
Change default URL type to 'None'
since majority of achievements shouldn't have documents linked to them
Store achievements in the database
Don't create new object then editing existing one,
also set achivement types combobox state then entering edit mode
More careful update for achievement records
