Few more updated for 4.5 move:

• Replaced all instances of mx:datagrid
• Fixed an issue where AdvDataGrid Headers were blank
• Fixed an issue with the custom tooltips
• Fixed an issue with the open report screen throwing an error
• Fixed an issue with minimizing dynamic panels throwing an error (only occurred when coupled with the dock bar)

Other stuff:

• Created a default CSS and theme to match blah white of most basic flex spark components
• Wrote a data descriptor for the report navigation tree so the hierarchy is correctly displayed and navigated
