Unified log file delimiter problem

[jdalbey]

The unified log file uses a comma to delimit fields. But Activity Log operators.txt file uses comma to separate last name and first name. So if a name gets written to the unified log the name separate gets seen as a field delimiter. Note, we desire to present names in drop down as Lastname, Firstname, so keeping operators.txt as it is may be preferable.

Currently, the first line of operators.txt is blank. Neil may need to remove that.

Changes made to Login.java (in tmcsim.client.cadclientgui.screens) in r639

• Remove appending anonymous trainee, just put this entry in names file if desired.
• Change studentnames file format to lastname, firstname - put in dropdown list this way so it's easy for user to scan the list for their name (assuming data entry put them in alphabetically).
• Once a name is selected from drop down, Reverse to firstname lastname with no comma for display in banner and in CAD comments log. If name lacks a comma, use it as is.
• Skip blank lines in studentnames file.
• Enable Password field (so secret dispatcher password can be entered)
