REPRODUCTION INSTRUCTIONS
-------------------------
There are three issues involved, reproducible as follows:

1. Launch ControlPanel and navigate to Advanced tab
2. Press tab, Tree view does not gain focus => ISSUE 1
3. Even we gain focus using mouse click, selecting/deselecting radio or checkbox using ctrl+space does not show where we are after the state change => ISSUE 2
4. Navigate to Security tab -> Choose certificates button
5. Press tab to navigate to components of certificates dialog
6. On empty table, we cannot figure out where the focus is and we may not know whether to press tab (navigate within table) or control+tab (to come out of table and navigate to other controls) => ISSUE 3


SUGGESTED FIX
-------------
Issue 1 - AdvancedPanel.java
Implement FocusListener and add to tree

Issue 2 - TreeRenderer.java, AccessibilityUtils.java
Added method which sets line border for a component on focus gain and reset to custom border otherwise. The method is called for tree component checkbox, label, radio button with empty border as custom border.

Issue 3 - CertificatesDialog.java
Create table with one empty row to hold focus on table selection instead of having header alone. Also added a related fix - for a table which has only empty row, the export, remove and details buttons should be disabled
