Recommendation Tracker Code

Use new YesNoDialog.java
(I'm doing a bad job of checking in stuff lately.)

New dialog to display error messages in selectable text area.
Has "copy to clipboard" button that selects all in the scrollable text area.

(Meant to check this in a half hour ago)

Created new error message dialog with text area and copy to clipboard button.
New dialog is used to display shcematron messages from checking xccdf file.

Fixed some nits...

+ LoginDialog is NO LONGER ALWAYS ON TOP
- About dialog appears above the Login screen

+ Lock File clean up
- Lock file now utilizes java.io.File.deleteOnExit() instead of manually having to delete on exit
- Lock file is checked prior to parsing the XML instance document ..users no longer have to wait for the file to be parsed before being told they can't use the application!
- Lock file can be overridden: warning message presents a Yes or No option for overriding.

Some tweaks to XCCDF Import.
Removed unused combo box models from the AddEdit[Profile, Group, Rule]MainDialog.

Deleted unneeded cce info panel. cleaned up ui on the cc pane;l in general

Corrected bug 2822606 - check language drop down was not reflecting the selected check language

- removed unneeded log message
- rearranged application menu items

+ changed cache initialization method to avoid invoking the setters for cell text values and cell tool tip text

+ Added a preventative null check to AbsCachedTextRenderer.initCache(...) method
